You are about to read my personal thoughts on both cameras. This report is written on my own feelings with them. It will be a complete amateur point of view (cause I'm not a pro), full of bad English (cause it's not my native) but hopefully - it will help some people who're deciding between these two.

Introduction

I started my photography digitally straight from the beginning. So I never owned any film camera or lenses or other gears before. But I had heard enough about Nikon and Canon reputation in photography world. Back in 1995, my very first digital camera was Kodak DC40 (wonder if you'd know it?), followed by Nikon Coolpix 990 (1999), Coolpix 995 (2000) and Coolpix 5000 (2001 until now). After a few years of using the compact digital camera and learned all of it's limitations, I then longed for the SLR body for a better functions and capabilities. I was waiting patiently for the price to come down. Finally, in Jan 2003, the lower end digital SLR body like Nikon D100, Canon D60 became affordable for me.

I liked to try both Canon D60 and Nikon D100 but at that time, the D60 is very hard to find and there was a rumour that the product is discontinued (or in the other word, there will be another one coming out) corporate with the reviews of these two that favors the Nikon D100. So I ended up purchasing D100 and started learning about digital SLR.

Nikon D100 is an impressive camera with it's feature and functions. Learning Nikon D100 is very easy for me as I have been using Nikon Coolpix cameras for years. For those who came to this way just like me will be very pleased with the capabilities of the SLR body which completely exceed the simple point&shoot camera. Later, I also learn that to get great pictures - we need a decent lens. Or the other word, the lenses play more important role than the camera body. And buying the camera body is just a start, there are a lot more to invest.

Then, in March 2003, Canon releases the D60 replacement - the Canon 10D. Of course, getting hands on this camera takes a while since it's a hot cake and still hard to find it in stock even now. Finally, I received my first 10D in April. The Canon 10D is also a very sweet camera, there are many things that are different from the Nikon D100 and since I'm having both in my hands now. Can't resist to compare both.

 

Comparing both cameras

Since this is so informal. I just gonna go through each topics at my own will.

1) Looks and feels.

Canon 10D has a Magnesium alloy body which feels rugged and cold to touch while D100 , even feel the same but according to one source, it's made from high impact plastic with metal substructure. Obviously, the D100 is taller and lighter while 10D is shorter and heavier. Holding them in my hands, D100 feels more like holding the camera which may be it's ergonomic design or it's weight. The power switch is in the perfect place and both the wheel controls are just right there with your thumb and index and feel very comfortable to shoot with one hand. Holding 10D, it feels like holding a brick because of it's shape and weight. Even though it has more added curves (comparing to D60). Nikon D100 feels better.

They both came with the same accessories - 1 battery, 1 charger, no memory card, 1 camera strap, TV and PC connector, CD software, manuals. Another thing is D100 come with the clear plastic protector (Nikon BM-2) for the LCD which is a big plus.

The build quality in details e.g. battery door, CF card door - the Canon 10D is better and more rugged. But in general and the major point of view, they're both well built.

D100 body is taller than 10D which becomes a minus for me since it does not fit my camera bag as 10D. Also when you attach the lens on D100, it tends to tumble down to the front due to the lens' weight. The shorter 10D's body allow both the camera and lens to stay flat and nice on the table.

 

2) AF

The D100 AF is fast and accurate. It performs very well in low light. This is one of the major winning area of D100 over D60. Canon 10D is supposed to have an improved AF over the D60. Canon 10D has 7 AF areas and each square is so tiny compare to the focus areas in D100 (5 bracket areas) which are big end more practical to use.

There is no flaws about AF in D100. It does a perfect job and make me wondered how much better this could be in the higher models like Nikon D1 series. Unfortunately, the 10D does have some issues. There are many discussions about front/back focus in the dpforum. I, for one, was having problem with back focus and have to send the camera back to Canon repair service center which still didn't fix the problem. Finally, I got the 2nd 10D which can deliver the more accurate focus.

From shooting both cameras : D100 focuses better with no doubts. At the same intentionally dim environment where the 10D couldn't focus, the D100 still can focus without helps (I mean AF assisted light, etc).

Shooting the test chart ( I learned all this from testing my front/back AF with my first 10D) with both cameras make me know that D100 delivered the accurate focus point with very minimal errors and doesn't need a lot of controls. My 1st 10D before fix always slightly back focus at all time and then had completely gone wacko after calibration done at Canon Factory Service Center in NJ. My 2nd 10D can deliver the dead on balls accurate focus with many controlled variables. read on. In conclusion, it takes more work to get my 10D to pass the test while the Nikon D100 doesn't.

To test your 10D, it's very important to control all the variables. You'll need to use tripod, delayed shutter (timer or remote cord), mirror lock up (if the shutter is too slow). The famous test chart can be downloaded from here. The 10D need adequate light source and the square area need to be right on the target.

If that square just happened to cover a bit to the right, you'll perhaps get the front focus and vice versa.

The details about how to shoot the test chart can be read at the above web site (that you downloaded the test chart). My only suggestion is to shoot multiple shots (at least 3) for each focal length.

In the low light, the D100 will use the AF assisted light (the bright light in the front that do the RED-EYE reduction job and flashing for the timer shutter release). This light can be turned off and most of the time D100 can do the job well without it. Canon 10D doesn't use this light (it's used only as a timer shutter release indicator) but will fire the short bursts of internal flash to help AF. I found this very annoying since the flashing light is what we're using to provoke the seizure electrical activities during the EEG (Electroencephalography) and there was a report of seizure induced by the same kind of flashing light from the TV. You can turn this off in 10D as well but then, it can't focus in the dark!

Both 10D and D100 can use the infrared AF assisted lamp if you connect them to the external flash. Honestly, if I were to shoot in the dim/dark condition, I'd shoot with the external flash which then the IR assisted AF will be used. So the lack of in-camera AF assisted lamp doesn't bother me.

My first 10D (serial no 0302xx..) did have problem with an inconsistent back focus. After I have my replacement (the 2nd 10D, serial no 0402xx...), the focus seems to be more consistent and accurate. However, my experiences of using all those - D100, old 10D and my current 10D, I can not be very confident shooting 10D with the narrow depth of field like I can with D100. Either I have to increase depth of field (mainly by increasing aperture) or shoot the same thing multiple times. With Nikon D100, I feel more secure with the AF.

So, for AF. The Nikon D100 wins (probably - not a lot : this is only when you got a non defective10D unit like my 2nd one).

 

3) Flash

Internal Flash

The internal flash of 10D doesn't pop very high above the lens so it can cast the shadow with some lens at some focal length while the D100 suffers this problem much less. . I found the internal flash of 10D is almost useless due to the above reason. The structure of the hot shoe on 10D is also more delicate or in the other word - easily broke. My 1st 10D had this problem because one of the tiny button underneath the left rail (see picture) fails to stretch all the way up and kept telling the camera that the ext flash is still on. That made the int flash refused to pop up and is one of the reasons that I sent it back for repair. The int. flash of D100 will pop up mechanically which is very convenient and the hot shoe is solid without a black paint. No worry about sliding in/out the ext flash. The D100 also allows more controls which you can choose from a regular mode (Front curtain sync), Red-eye reduction, Red-eye reduction with slow sync, slow sync, Rear-curtain sync and slow rear-curtain sync. In 10D, you can find each mode of flashes spread all over the place, hidden unorganized in the custom menu. So simply spoken - D100 has more solid (and simple) int. flash structure and better flash controls.

External Flash

Comparing between the top model external flashes of both- Nikon SB-80 DX and Canon 550 EX. They are both made in Japan, (or MIJ which is one of my personal criteria for buying stuffs). I like SB-80 better just because It's smaller, looks cool, better mounting system (easy and stronger) and the screen display is big and clearly seen (please note that SB-80 DX come out later than 550EX). It also comes with the white bounce card and the dome diffuser. Physically, the 550 EX just look like a brick (again ?!) due to it's size (much bigger) and weight. The display screen looks kin da obsolete with small text display. The one good thing about 550EX is the mini stand for remote wireless flash. Also, the flash head control in SB-80 DX is better - only 1 switch will let you turn and tilt while on 550 EX they're separated. These 2 flashes both came with a mediocre pouch or bag and use 4 of AA batteries. One observation is the 550EX is significantly louder (yes, that high pitch moaning noise).

Functionally, I like the Canon 550 EX better. My flash pictures in D100 tend to be underexposed (can be fixed easily if you're shooting RAW) while the 550EX plays along very well with 10D and give a nice and well balanced shot. That perhaps has nothing to do with the flash itself but it's the whole system. I also like the wireless and High speed sync flash in 550EX. The wireless control on 550EX is on the physical button which is very easy while the SB-80 DX will need to go through the menu.

So by conclusion. D10's internal flash is quite useless and this demands getting an external flash. Having 550 EX (or others) is a must and then will does all the job and also answer the question why the higher model like Canon 1D, 1Ds or Nikon D1 series don't have internal flash.

 

4) RAW Conversion Software

Nikon D100 comes with the Nikon View (NV) 5.0 (you can download 6.0 now) which is much better than Canon FileViewer Utility v1.2 (FVU) that come with 10D. The Canon FVU is extremely slow and it refreshes (with that slow speed) every time you apply the changes. This slow speed has made Canon FVU become completely useless to me.

Canon doesn't offer a better version of the software but Nikon offer the Nikon Capture (NC) for $99 which can handle the picture fantastically. It has many controls and it can turn a bad shot into a stunning image. The NC also can do the batch conversion in just a snap. It'd be my next purchase if I'd stay with Nikon.

I have been looking for the good 3rd party software that can handle Canon proprietary RAW format (CRW file) and have not yet found anything like Nikon Capture. Many of these software that I tried has some limitations and didn't make me feel it worth the money. Not even with the one that most people like - Capture one LE. This lack of good RAW conversion software in 10D has made me tend to shoot jpg in some unimportant event while I always shot RAW with D100.

I do not find any benefits of having the jpg tagged with CRW file in 10D. Because these jpg files are completely embedded and nobody (no other software) can see it except for Canon FUV or other Canon's software. And then to extract these files, you still have to wait at roughly the same time you spend to convert them from RAW. And these tagged jpg just make the CRW file bigger than it should be without.

Also it's deserved to mention that shooting RAW in 10D will give you 2 files simultaneously - CRW and THM. I found this is annoying since you have to copy both or delete one of these when you transfer the files. If you put the CRW back into the CF card without the THM, the camera won't see that image.

 

5) Noise

This is the one thing 10D is a clear winner. This is mainly due to the differences of image capturing chip CMOS (in 10D) and CCD (D100). If you have been using the point & shoot digital camera before, like me, you'll be amazed with the lower noise level in the digital SLRs (it has bigger physical CCD size, so it has higher signal-noise ratio). Look at the shot with the lens cap on for each camera and you'll see that both D100 and 10D (10D image is cleaner when you look at the entire image by click on each cropped) has much less significant noise and dead pixels which can be appreciated even with the cropped images.

These are cropped images from the following 3 cameras shot with the lens caps on, M mode, 10 s, f/8.0 at ISO 800. Click on each image to see the entire shot

Nikon Coolpix 5000

Nikon D100

Canon 10D

There are many factors that impact the noise level e.g. the ISO, the temperature (noise is significantly higher in the hot climate), and exposure of the picture.

We have already pretty much known that Canon 10D has lower noise. I wanted to point out that the noise from Nikon D100 in a regular exposure time is not too bad, actually quite good. If shooting in the adequate light and any shutter speed that is higher than 1/60, the noise from both camera at the ISO lower than 400 is quite good and usable. For 10D some shots at ISO 800 is unbelievably clean.

This is the test image that I shot in the control settings. Canon 10D + Canon EF 24-70 2.8 L USM and Nikon D100 + Nikkor 24-85 mm ED AFS. Please do not compare the image quality since both lenses are quite different in quality (and price) and these shots are made only to compare noises between the 2 cameras.

As you know, the noise will become more noticeable when you enlarge the image. So from the above test image, I have enlarged it to 100% and placed a crop in the neck area of the this ceramic.

You can see that Canon 10D is a winner at every ISO level but noises from D100 is not too bad. Actually, to be able to get the shots is perhaps more important than noise levels or inability to shoot at all. There are many software that will eliminate noises e.g. Neat image or the noise reduction (NR) bar came with some RAW conversion software (which you have to shoot RAW) e.g. Nikon Capture, Breeze Browser, etc (unfortunately, not NV 6.0 or CFUV 1.2) will help a lot. And whether or not the noise will be seen, it depends on what you do after. If you leave the whole image cropped or use it for a small thumbnail or display on the web site, those noises won't be noticeable (see picture ->). But if you are gonna blow up and print that image, now the noise is your enemy.
A shot at ISO 3200 from Nikon D100.

One thing about ISO adjustment that should be mentioned is the range adjustability of each camera. The 10D ISO started from 100 and can be increased by doubling the number from 100 -> 200 -> 400 -> 800 -> 1600 (only 5 levels), while the D100 started from 200 and go for 250, 320, 400, 500, 640, 800, 1000, 1250, 1600, Hi-1 (3200) and Hi-2 (6400). Honestly, D100 fine ISO adjustment is more useful and the higher ISO at 3200 and 6400 can save you in some rare circumstances.

Now the big difference in noise issue of these 2 cameras are the long exposure shot. The CCD in Nikon D100 does the mediocre job with the long exposure.

I did a comparison by shooting night images from the rooftop of my apartment. The picture on your right is the entire shot. Both cameras (D100 + Nikkor 24-85mm, 10D + EF 24-70mm) are on tripod, ISO 200, M mode and the exposure time was set at 6, 10 and 30 seconds.

For Nikon D100, there are 2 series of shots - NR on or NR off.

Both cameras are shot with auto WB, but for each series of shots took a while and the sky keep changing all the time. You may notice the color between each shot are quite different.

The shots are made in RAW (CRW and NEF) which then convert to a readable format by Nikon View 6.0 and Canon FVU 1.2.


The images below are the crop at 100% around the Chrysler building of each shots we took. Then you can click on each thumbnails below to see the entire images.

D100, S 30", A 16ISO 200 NR -ON

Canon 10D, S 30", A 16, ISO 200

As you can see, the Canon 10D produces clean images at any exposure time from 6 sec toward 30 second (you can go for more !) with very small increasing of noise. This render the un necessity of having Noise Reduction job. Meanwhile, noises in D100 is more visualized than 10D's and at the extra long exposure 30 sec, the noise is visibly very clearly at even the crop picture. But the NR function works great, too.

The NR in Nikon can be turn on or off. It does take a very long time (longer with longer exposure) to finished and while it's working, the camera will be in a locked state - can't use, can't change the settings. It is a big downside of this feature. BTW, but this very same camera NR can be done later in Adobe PS.

In conclusion. Noises from higher ISO with normal shutter speeds (that you can hold with your hands) are not too bad for either cameras. But noises from long exposure is significantly less in Canon 10D. To each his own, if long exposure/night shots are so important to you. We got a clear winner here. I have known somebody who is so loyal to Nikon and never wanted to switch but he bought the 10D for this purpose only !

 

6) Features and Functions.

You will find that I am helplessly biased to nikon in this area since I came from Nikon Coolpix and somehow I've grown accustomed to using Nikon system. Shooting both D100 and 10D are quite similar but also quite different.

Nikon D100 function dial looks primitively classic. Not a lot of shooting mode you got, the most automatic mode would be P (Flexible Program) in which you let the camera choose both A (aperture) and S (shutter speed) for you. M = Manual, A = Aperture priority and S is Shutter priority.

As you can see that the ISO, WB, Quality (image type, size), AF mode control are in the same knob. Some people complain about this design because you have to turn the dial out of your shooting set to change those. I find this annoying but not too terrible. You actually can control all of those (ISO, WB, Q, AF) through the menu display as well.

Canon 10D came with more idiot modes that called Basic zone and the others called creative zone. People who came from Canon or always shoot auto mode before will love these Basic Zone. I do not find uses of these much except for the sports. Note that these basic zone will record only jpg type (no RAW). It's a quick combination of settings that suit for each events.

For the creative zone. Canon used a different abbrev. which looks more complicated but pretty much the same thing. P for flexible program, Tv : shutter priority, Av : aperture priority and M : manual. A-DEP is something I start to get fond of, the camera will choose the A that provide the widest depth of field. This mode will entitle you to use dynamic AF area and you won't be able to choose your own S or A but will be confident that subjects in the shot will come out well-focused.

I will not go through every details because it'd make this simple report too long. I'll mention what I like and what I dislike on each camera.

-Canon 10D menu is easier to browse. The menu looks more novice and sophisticated and browsing with the quick control dial is just a snap. The control menu in D100 looks quite primitive and the arrow keys just need more effort to get what you want.

-As you know, D100 will display the remaining shots (in memory card) at all time (even off) and has instantaneous start up while the 10D will require a few second before you can shoot. I don't find this delay much problematic but some people do. Having the remaining shots always displayed is a nice touch.

-D100 can go forever with one battery while 10D does not (but still not too bad compare to battery usage in p&s digital camera that uses LCD as a VF).

-Like I said before. I like the flash control settings in D100 better. In Canon10D, these flash control can be found all over the place through the menu and custom menu, not quite handy. One thing about the slow sync. There is no slow sync for flash in Canon10D but you'll achieve the same thing by choosing the Basic Zone- Night portrait. If you want the RAW shot of slow sync, you'll have to shoot in Tv, Av or M mode. For P or A-DEP with the flash, the S will fixed at 1/60 with varied A. When I was shooting Nikon, my most commonly used mode is A. When the flash will be used, the shutter will be fixed at 1/60 which then I can dial A to wherever I want (if my flash can reach far enough). To get the Av mode with flash in Canon 10D works like A in Nikon system, you'll have to go to custom setting no. 3 and order the Flash sync speed to fix at 1/200.

-As mentioned before, changing ISO, WB, Q, AF area is easier in 10D. You don't need to get out of your shooting set.

-When shooting in the dark with 10D, I can't see which Mode that I'm using (M, Av, or else ?) because it doesn't display anywhere, not in the top LCD, not in the VF (View Finder) and the control dial doesn't light up. I am completely blind with this, not until I get a small torch or some light source to look at the knob and see where I am. Also the LCD light on 10D will automatically go off very quick (in roughly 2 sec), not enough for me to check everything and you can't control the length of this light. In D100, the light will stay on until you turn it off and you can set for it to come up when any button is pressed. Not to mention that D100's VF displays a lot info, enough that you don't need to look at the top LCD much while Canon 10D's VF doesn't do that and yet small enough to strain my eye muscles. That make a purchase of Canon Angle Finder C became necessary and very helpful for me.

-Some sort of battery saving strategy is going on with 10D, besides of that LCD light that go off too quickly, also the auto-metering status of the camera is gone too quickly, too. After you 1/2 press the shutter button, you have only about 5 sec to make changes on A or S, o/w it will be gone and you have to 1/2 press again. This is very annoying to me compare to D100 which you can set the auto-off time for this auto-metering from 4 sec to 30min. I left mine on 30 min and do not feel any losing of battery power.

-Did I tell you that Nikon D100 VF is much better (easier to see) with a lot of info and grids? The grids display in D100's VF is very helpful when shooting landscape or buildings. Of course, you can turn those off if you don't like but you can't have it in 10D.

-Controlling the exposure on 10D is much easier through the quick control dial. This could be a double-edged sword since your finger may accidentally change it unknowingly. That's why they made the lock button for it !

-Deleting multiple files in 10D could be painful since you can not choose multiple images before command the order "DELETE" like you can in Nikon D100 (and also other coolpixes).

-Folder system in 10D is terrible, you can't designate your own custom folder and the camera will automatically start the new folder when the running number reach every hundredth. This is annoying when you are transferring the images. Also shooting Canon RAW, you'll automatically get 2 files for the same picture - big CRW and small THM. Again, annoying for transferring. You can delete the THM file as long as you don't want to transfer that CRW file back to the CF card cause the 10D won't read the CRW without the corresponding THM file that it creates !

-D100 will let you designate the folders and the images stay in the same folder until you change it. You also can key in (painfully slow) your text comment into each picture !

-Format the CF card in 10D is much faster and easier.

-Taking custom WB (Nikon called Preset WB) is different in both. I don't know which one is actually better but I like Nikon's way. In D100, it takes measurement by have you release the shutter after the gray (or white) card that placed and filled up in the viewfinder. Then, the camera will tell you "good" or "no good". In 10D, you simply take the real picture of that gray card and it's stored in the folder as 1 picture. The good thing about this is you can keep it and memorize the setting and come back to use it again anytime. The bad is it'll take space in the CF card unless you change the Q to the lowest (which again, takes extra process) and also I do not know which WB I should set when taking the picture of gray card for custom WB. In 10D's manual, it says anything but I bet that gray card look completely different between each WB settings !

-Canon 10D has automatic image rotation detector which work miraculously. These designated rotated images will show up correctly only in some browsers e.g. CFUV, Canon Zoom browser, BreezeBrowser, etc. It'll be useless in some program which doesn't read this indicator e.g. ACDsee v.4.0.2 or QimagePro, etc. But all in all, it's nice to have it.

-Canon 10D has some extra features about printing e.g. direct printing, DPOF (Digital Print Order Format) which doesn't give me any benefits. I still require a PC and some post-processing jobs before printing but this could be a benefit to somebody.

-NikonD100 came with the LCD protector (Nikon BM-2) which is a hugh plus for me since I'm scratch-protecter freak. It's something I was born with and I proudly admitted that I am obsessed to protect every scratchable surfaces on any gadgets in my belongings. Obviously, some people do not care about this. I, myself, was desperately looking for something like Nikon BM-2 that work on Canon 10D, something protecting but clear enough to see through and meanwhile - easily removable for cleaning. Nothing a like Nikon BM-2 the closest thing on earth could be the DA protector (choose the one for Olympus) which is reasonably priced. The DA protector use the sticky tape to go on the original screen which mean that it doesn't easily come off and it's pretty thick but yet very clear to see through. Some careless folks will recommend you do not put anything on because you can change that original window by yourselves. I do not aware of how to get that LCD window part but I can confirm you that it can come off and it will surprise you with Sony brand inside !
when I was removing the DA protector from my 1st 10D, the original LCD screen came off and this is what behind Canon's logo. Click the image to see the bigger.

-Shooting panorama ? In Nikon D100 (actually, since Coolpix), you'll be able to lock the auto exposure and taking your time to pan-shooting your shots until you finished and unlock that auto exposure. The AE lock in Canon 10D doesn't hold. After you pressed that lock button, it stayed lock only if you keep the AE stayed on by either continue taking picture or continue 1/2 pressing the shutter release (AE stay roughly only 5 sec after you 1/2 press). So shooting panorama with 10D could be the pain. Either have to do a quick succession of shots or go back to measure AE again (praying that it doesn't change) or completely use everything manual.

-I like the Canon remote shutter release TC-80N3 (you can buy other cheaper models) that can connect directly to 10D. In Nikon D100, you need to have the vertical battery grip to connect the electronic remote control. But, in D100, it allows you to use the conventional mechanical remote shutter cord.

-Be careful, opening the CF card door in 10D will interrupt the CF card writing which means that you'll lose those writing images. Opening CF card door in D100 won't do that. Turning the camera off while the D100 is writing (green light flases) is not recommended by Nikon but the camera still continue to write until but ejecting the card or pull the battery out could make you lose the buffered images. In 10D, there are sensors that detect the CF card door and also the battery door and make the camera know it's open or closed.

-Buffering in 10D will allow you to shoot more shots (9 full jpg/ 9 CRW) in continuous shooting compare to D100 (8 full size jpg and only 4 uncompressed RAW) and this will make shooting sport in D100 with RAW format almost impractical. One funny thing is - in 10D, when the buffer is full and the camera is flushing images to CF card, you won't be able to review your images (busy... busy ... busy..., I thought that what we normally try to do when we can't shoot) but you can in D100.

-Preview image. Well, they both have pros and cons. D100 preview give you 7 different types of previews (image only, image with file number, image with full file name + date + time, image with 1st page info, 2nd page info, image with histogram, mage with blinking highlight). In 10D, there only 2 previews, image without info (file name, S, f) and image with info (histogram, ISO, FE, Exposure compensation, Q, WB). Some of these may be excess and unnecessary but the one with blinking highlight is very useful (and this is not available in 10D). So you can adjust exposure or do exposure bracketing and this is what image preview is mainly for (in my opinion). For 10D, first it doesn't provide this info (but you can see from the histogram, too) and secondly the LCD screen can be too bright and you don't know that your image is under-exposure until you see it on your calibrated monitor.

Anyway, the zoom in function in 10D is easier, better and allow you to 10X zoom in and out. Navigation to each area of image is a little wired since you can move in one direction at a time while D100 will let you zoom in only 6x but you can browse through each area easily with the multi-selector button (the one with 4 arrows). Meanwhile, the 10D preview stays forever until you shut the camera off or press shutter button but D100 preview will automatically go off in about based on your setting (Custom #6) from 10s to 10min. The auto-off review time that you set in 10D's menu is only for auto preview. It's ironic to say that the camera is trying to conserve the battery power but doesn't control the major draining LCD usages.

-Bracketing (AE, AE with flash, Flash only or WB) in D100 can be done easier cause there is a physical button present compare to 10D which you have to go through the menu.

-Metering. Spot metering is not available in 10D and the closest to "spot" is partial metering which cover 9% (Spot in D100 : 2%). I don't use much spot metering and that 9% will be fine for me. But I wondered between 35 area evaluative metering in 10D and the 3D 10 segment matrix metering in D100, which one is better ?

-Self timer in D100 can be chosen from 2,5 10 or 20 sec while in 10D, it's fixed at 10 sec.

7) Battery

Should I mention again that digital SLR will not allows you to use LCD display as a VF (the mirror will block the way). This tremendously save the battery juice. When using Coolpix, I need to carry around at least 3 more spare batteries. With the digital SLR, battery lasts very long unless you use a lot of LCD for display. However, there are still some differences between these 2.

For Nikon D100, the EN-EL3 is rated at 1400 mA and it seems to last unbelievably forever. Leaving the camera on doesn't seem to drain the battery (unlike 10D) at all. I remember shooting all day with only one battery and still can't deplete it (try to use the other 3 in my spare). Also the battery indicator on D100 is better since it tells you at 3 steps before it actually exhausted. This battery indicator is also shown in the VF. This EN-EL3 will automatically charge the internal battery (not replaceable) that keep time and date stored.

There are 2 batteries in 10D. One is the lithium button battery CR2025 which store date and time. Another is BP 511 for 10D rated at 1100 mA and it doesn't last as long as EN-EL3. I was surprised to find that the camera is draining the battery when you left it on but not using it ! I have never achieved the number of shots per battery advertised by Canon. The battery indicator also has only 2 levels, full and partiall and next thing you know, it's out !

 

8) Cost of ownership

The price of 10D (street price = 1499 USD) is significantly lower than D100 (used to be 1999.95 USD, now (as of April,03 -it's 1699.95 USD) even it came out later. In the digital SLR world, the cost of lenses could be much more substantial than the camera body. Actually, since now the camera body is digital - like the PC, it doesn't hold the value over time. So paying a lot of money for the camera body is not worthwhile.

By average, the prices of Canon lenses and accessories/lenses seem to be more reasonable than Nikon's (some items - Canon may be more expensive e.g. the Canon angle finder is more expensive than Nikon's). They're both made in Japan and they're both supposed to have the same quality, even though I tend to like Nikon's gear better only because the cosmetic reasons. I will omit to discuss about the lenses since I don't have much knowledge about them. To my feelings, Canon has more newer designed lenses than Nikon's. The feature that called "USM" or Ultrasonic Motor (something that make the lens focus faster and quieter) or AF-S in Nikon, these feature are available in Canon lenses more than Nikon's. Almost all Canon's lenses now are USM.

In United States (at least in NYC), you can buy the "gray market" stuffs. The gray market or sometimes called "imported" are authentic since they're made by Canon or Nikon. Only they're in the states without going through Nikon USA or Canon USA. So mainly, the store who is selling them (usually big stores) will be responsible for carry the warranty. And of course, the gray market stuff is a little bit (sometimes, quite a bit) cheaper.

The reason I talk about this because I am impressed that Canon USA who will repair any broken Canon's parts even though you bought them as a gray market while the Nikon USA will not. See the differences ? So Canon is always Canon, anywhere in the world but Nikon is not !.

 

9) Sensor Dusts

This was a new topic to me since I came from p&s digital camera.Click to see the bigger Now I've learnt that in digital SLR camera, occasionally, the small dust particle can enter the camera and make it's way to reach and stay on the sensor (CCD or CMOS) surface and cause speckles in the images. Normally, these dusts won't show up until you're shooting something smooth and has continuous tone like sky with a small aperture. (To appreciate your dust the best, try shooting sky with f22)

Well, I have not owned 10D long enough as I have owned Nikon D100. The dust issue is truly annoying and you'll need to learn how to clean it and how to live with it. Can't deny that dust is every where and the camera was designed to have interchangeable lenses, so it's inevitable to get dust on CCD/CMOS occasionally.

Now, there are many people who believe that Canon 10D has less problem with this because the CMOS seems to use less electricity and somehow generate less static attraction to dusts. I have heard from some people that they don't really appreciate this. The CMOS on 1Ds or 10D could capture dusts as well. To me, owning the 2nd 10D for 7 days - I have already had the dust that require the swab&wipe method. So I can't really appreciate this less dust possibility on 10D either.

If you want to read more about cleaning dusts on CCD, read this and this.

Anyway, I want to praise Canon for giving us the ability to clean the sensor with the battery supply. In Nikon D100 or D60 or D30, the sensor cleaning requires the AC adapter. This is actually not quite an improvement for upgrade from D60 since D60 package supply the battery charger with AC adapter. But in D100, if you don't buy a separate EH-5 AC adapter (another $79), you can't effectively clean the sensor. The cheat way is to tell the camera to stay open the shutter (use bulb) and clean it. But this way, you'll lose one finger that keep pressing that shutter button and also the sensor still active while cleaning (may attract more dusts).

 

 

10) Image quality

I think both cameras can produce the very good images. Like I said before, the lens and the photographer are way more important than the camera itself. The good photographers can produce the excellent images from one of these cameras if they have good lenses. To me, I don't see much differences in image quality between these 2 camera with the comparable lenses. Shooting RAW has now become my habit and the image quality is just superb after some digital darkroom work. Only that I wish I can find a better software for Canon's RAW manipulation. The one like Nikon Capture.

Final Conclusion

I have hesitated for quite some time, holding both cameras in my hands. Learning Canon system took me weeks to get used to. Also facing problems with back focus issue and internal flash with my 1st 10D. I almost decided to stay with Nikon D100 since you can see that to my feelings, I like D100 and Nikon very much (it's funny that my personal text-proofer was wondering that I actually chose Canon after he read this review ?). After all, I got the replacement 10D that actually works. Comparing just only the camera body isn't enough to entitle you to either Canon or Nikon world. There are many other factors including lenses, accessories and which camera suits you better. In reality, I can not stay with both since they have different expensive expansions beyond the camera body itself. I finally decided to stay with Canon 10D because it's a digital world and Canon has shown to me that they are aggressive in improving their products in the reasonable time. Being with Nikon for years, it's very obvious that Nikon just slowly making their move even though it seems to be more robust and very conservative (should be good with the film camera).

Finally, choosing any camera is up to you. I can't decide or answer for you. You may find yourselves more comfortable with Nikon. Any cameras in a good photographer's hand can produce the stunning images.
