Canon 20D: Raising the Bar for Prosumer Digital SLRs

Noise
The noise test consists of pictures of our studio shot taken at increasing ISO levels to show the effect on the image. The pictures were taken after resetting the cameras to their factory default settings. The cameras were then set to record with the highest quality option with manual WB. Aperture priority (f/11) was used. The 20D has been set to Parameter 2 while the 10D is set to Standard. A Canon 50mm Macro lens was used on both cameras.

Across the board, the 20D dominates over the 10D in its low noise capabilities. Even at ISO 200 and 400, the 20D produces clean images while the 10D images begin to get a bit grainy. By ISO 1600 and 3200, the advantages of the 20D are astounding. While the 10D takes on serious detail loss and discoloration, the 20D retains significantly more fine details. In our noise test, it is safe to say that ISO 3200 on the 20D is roughly equivalent to somewhere between ISO 800 and 1600 on the 10D. This is a very important advantage for 20D users because it empowers them to shoot in darker lighting with much better results than the 10D.

What exactly is the point of these camera reviews? As I wrote several months ago, Anandtech is a gadget/hardware site, not a photography site. If you want to reach the photography community (like the rich folk who hang around DPReview.com, spending $1000 a month on lenses, and are ready to click on lots of advertisers' banners), you should do something novel. I suggested reviewing portable photo storage devices (e.g. the Epson P-2000, Archos AV-480, and Nikon ), but nobody listened to me. Suit yourself. As soon as you review any of these gadgets, you will find yourself on DPReview.com, gizmodo.com, and other popular sites. But don't listen to me, I'm just a yuppie male, age 28-40, making a good salary; it's not like your advertisers care about my demographic or anything.Joony - Friday, November 12, 2004 - link
I love my 20D, check out my photogallery,http://www.pbase.com/joony

You may also want to look at the DCRAW - Digital Camera RAW. It is a open source program for reading RAW files from most camera RAW files.DCRAW vs. Canon D60: http://www.aim-dtp.net/aim/digicam/dcraw/

Woodaddy, thanks for your comments. A Canon 50mm f/2.5 Macro lens was used for all the tests except on page 11 (where each picture lists the lens used beneath the thumbnail). I've also amended the other image quality pages to indicate the use of the 50mm. Sorry for this oversight.WooDaddy - Thursday, November 11, 2004 - link
I missed something critical here. Let me know if it was posted. What lens are you using? Since DSLRs have interchangable lenses, the image quality is directly related to the lens used. If not listed, you really want to say that for reference in you image quality tests.#8, #3 I've picked on Stephen when he first got started on his reviews. He's getting better and IMO he's doing a great job. Now mind you, dpreview is for photogs/techies with an emphasis on photogs. AT is the converse; techies/photogs. I would consider ease of use and image quality and control to be a focus in a review at dpreview. Technical features would be the focus at AT....
Personally, I'm a photog more so than a techie camera guy. I'm doing quite well with my Nikon FE2 manual camera (with Acer 2740s film scanner) and Minolta G400 backup.

Wau, this thing makes some great pics! Way too expensive though.Gatak - Thursday, November 11, 2004 - link
#3 Yes dpreview has many good articles. But I think this is a good start anyway. Dpreview is very technical and doesn't really provide much explanation of technical stuff. This is something I think Anandtech could advance in =) It is possible to have technical depth and yet have good, easy to understand explanations.ProviaFan - Thursday, November 11, 2004 - link
#4 - that's why we have the term "prosumer". It's (the 20D) better than consumer, which would be the digital rebel, but it's not in the league of 1D Mark II (even though it has the same resolution, the speed and build quality don't compare) or 1Ds - which are professional.stephencaston - Thursday, November 11, 2004 - link
#4, The 20D is often referred to as a Prosumer camera. Among the reasons are price, 1.6x cropping factor, sealing, built-in flash, and _optional_ battery grip.The 20D is aimed at amateur photographers looking to replace/supplement their existing film SLR or for those looking to upgrade from a non-SLR camera. I've also heard of pros buying 10D and 20D bodies as backup cameras. I don't think it would be fair to the 1D line to call the 20D a professional camera. It is very nice, but not quite pro ;-)

Nice article, I use both a 10D and a 20D and would like to see some ACR tests added to the CPU processing tests besides the emphasis on games to assist us in selecting the best hardware for processing digital images. One of the test that could be used is the Tom Fors ACR calibrator beta 3.http://fors.net/scripts/ACR-Calibrator/
