Resolving Fine Lines

Before reading this page, please refer to our Testing Procedures to see our methodology.

*For all image quality tests, a Canon 50mm Macro lens was used on both cameras.

We set each camera to ISO 100 and used the aperture priority mode to keep the aperture at f8. After shooting the RAW images, we set the EV (exposure value) to +1.0 and converted them to JPEG. Click on a picture to download the full-version JPEG converted from the RAW file.

Digital Rebel

We were hard-pressed to see any huge differences in quality between the Rebel and the 10D here. It looks like the 10D is able to hold its line resolution a little bit longer, but both start to lose resolution after 16. It also seems that the 10D does a better job trying to keep its resolution past 18 where the Rebel becomes one smooth line.

Digital Rebel 10D

The vertical line test proves to be very similar to the horizontal one. The Rebel begins to crack up just after the 16 mark, while the 10D holds out to a little past 17 before showing signs of degradation. Again, we can see that by the 18 mark, the Rebel and the 10D have lost any signs of individual lines. Overall, these two cameras have performed very similarly in our ISO 122233 Resolution test.

    everyone looking for the "hack"

    I don't agree. Why wouldn't someone start with a 10D? For example, let's say that someone has a sizable investment in Canon EF L lenses and wants to make the jump to digital? The 10D/20D would be a good choice for those who own a bunch of lenses and who don't want to break the bank on a digital SLR.

    I'm currently considering making such a move. The EOS 20D would be a fine addition to my EOS-1 and EOS-3. I could decide to get a digital made around the EOS-1 at a later time.

    Whaddaya think??

    Nice review, very detailed, with lots of useful information. Will you be posting an update based on the newly-released 20D?

    I think you did an excellent job in your review. I especially enjoyed the side by side noise and color comparisons. I thought the topic was very relevant and direct comparisons between the 300D and 10D are not that common. I thought the hands-on battery review was excellent as well. Every review adds something new and different. Yours was no exception.

    I find it unfortunate that some of the people here have a need to tear other people's work down. I appreciate your work and I think you did a good job. Thanks!

    yeah, i totally agree. First, there's no way anyone would START with the 10D. the 300D, maybe, but the person needs to be seriously wanting to get into photography. Otherwise, if all you want is a simple camera, there's no need to go with the "DSLRs". For MOST PPL, a fixed lens solution works just fine. Personally, i have outgrown a fixed lens solution, but i dont have the $$$ to get a real camera simply because the cost of lenses are $$$$$ compared to the cost of the camera.

    Besides, no one cares about any battles between the 10D and 300D. The battles are between the other $1000 DSLRs. So far, Nikon is winning imo.

    I'd have to agree with the majority of comments here. I'm sure stephen meant well by the review but I don't feel that Anandtech is an appropiate forum to discuss digital cameras. Dpreview is hands-down the best place for camera reviews.. Mind you, it is so because of the more photographic related points made during the review. Additionally, they focus on photogs not gadget lovers. A gadget lover wouldn't even consider a 10D, though a Rebel would be in their alley. (Personally, I have a Nikon FE2 with a Acer ScanWit 2420 and Minolta G400).

    I have a feeling the MAIN reason why this whole review was posted and even considered was what was noted in the last paragraph... a hack. Hacks/overclocking/deals/best bang for you buck all are issues that Anandtech readers love, hence the weekly buyers guides, overclocking tests, etc. This would have been best located as a post in the forums somewhere. Once I read that single paragraph, the jig was up and I was even more disappointed.

    Additional 2c:
    Anyone getting started in photography shouldn't use a 10D quality camera. Grasshopper, you must first realize it is the photographer, not the camera that takes great pictures. AF, AE, etc. should be regarded as luxuries not as requirements. Once you learn how to use a manual camera (Zone method, etc), one can appreciate automatic features. Same idea with digital cameras. Start small (S410 or S50) then move up to the big boys.

    ... phew... </rant>

    The resolution test was done in RAW mode for both cameras and then converted to JPG in PS CS with +1.0 EV applied.

    The rest of the image quality tests (including white balance) were done with both cameras reset to factory default settings and using the lowest compression JPG mode (Large/Fine 3072x2048). This allowed us to compare how both cameras process images using their default settings.

    Does anyone know if the image quality and white balance tests were shot in RAW or JPEG mode?

    Reason is the tests will be uneven. The 300D will sharpen the image slightly more causing a degradation in resolution. Also, the 300D does boost the saturation slightly. The shots need to be done in RAW only and those images need to be compared. If I missed the fine print, I apologize.

    Dpreview does indeed offer a far more comprehensive and frankly, believable review of each of these cameras.

    I agree that you should instead focus on the computer-related issues that are involved with these kinds of cameras. It would be *GREAT* if you would post a comprehensive review of the firmware hacks for the 300D that are out there or do an overview of the various storage options that are out now. Hell, you could do a comprehensive look at performance issues with new CF cards - which ones are really worth the money and with what cameras are they best suited.

    The D-Rebel cannot compare to Nikon's D70. Check it out. It is just slightly more expensive than the D-Rebel ($100 or so) and has many more features and better design / build. Reply
