Canon 1D Mark II ISO questions
From: (Carol R)
With the D60, I find I can get good quality at ISO 100 and 200. At 400 noise begins to be a factor. My wife has a 10D and after testing it for noise I would agree with your numbers, 200 looks good and 400 doesn't (for good sized prints and our tastes). The Mark 11 is supposed to be greatly improved in the area of ISO noise at higher ISO speeds. Just got one of these a couple weeks ago and it's a great camera. Haven't tested for noise above 320 yet but at 320 it's better than the 10D at 200. I am close to opting for this camera if this is true. Now I hear there will be new releases from Canon in Sept so I want to wait for that. No way they'll replace the Mark II that quickly (it's still in short supply) but it would be wonderful if they used the same 8 Mpix sensor in a lower price camera, either on the Elan body (10D Mark II?) or even better on the EOS-3 body (3D?). Unless you need the super fast autofocus and frame rate of the Mark II I'd wait a bit and see if they bring out an 8 Mpix dSLR on one of these cheaper bodies. Would love to hear from some folks who are familiar with the D60 and now have the Mark 11: On ISO noise and the difference between these two in this regard. And the same question to the 10D people who have shot with the D60 and now use the 10D. http://www.dpreview.com/reviews/cano...kii/page18.asp and scroll down for the 'Luminance Noise Graph' ... basically what it says is the Mark II noise at 800 is about the same as the 10D at 400, and the M II at 400 is about the same as the 10D at 200. At any given ISO the Mark II is better than the other cameras shown (Nikon D2H, Canon 1Ds, Canon 1D, Canon 10D). If you want to see a couple of samples look at these I shot yesterday ... http://members.aol.com/hiltonfotogra...z_crop_usm.jpg (600x400 actual pixels crop, if the file were printed 30x45" this is what 5x7.5" worth of detail would look like on my screen) http://members.aol.com/hiltonfotography/liz.jpg (the full image after downsampling for the web, the crop was just of the eye area) http://members.aol.com/hiltonfotography/humm_det.jpg another 100% crop, this shows how smooth the background is at ISO 250 ... this and the first shot were taken at 1,000 mm (500 f/4 w/ 2x converter) and this one shows how quickly it autofocuses, catching a hummer in mid-air. http://members.aol.com/hiltonfotography/humm.jpg (full frame shot reduced about 5x, the crop was of the head) I took 11 shots of the hummer and 9 were in focus and sharp. Any camera that can AF on a hovering hummingbird with a 1,000 mm lens (1,300 mm equivalent 35 mm FOV) is OK by me One more and I'll stop bragging about this camera ... http://members.aol.com/hiltonfotogra...ve_blossom.jpg .. this one prints beautifully at 12x18", as good as or slightly better than scanned 35mm film.

Canon 1D Mark II ISO questions
Would love to hear from some folks who are familiar with the D60 and
now have the Mark 11: On ISO noise and the difference between these two in this regard. And the same question to the 10D people who have shot with the D60 and now use the 10D. I have both 10D and D60 and use them in theatre photography where frequently lighting on stage can be relatively dim. I use the noise filtering in Adobe camera raw and sometines Neatimage to mitigate the high iso - low lighting levels noise. I find the 10D to show about half the noise of the D60: the 10D at 800 has noise range close to what I see in the D60 at 400, and I can use the 10D at 1600 and get very usable results (not my first choice but sometimes the only way to get the shots). I'll really be looking forward to the Mark II (or its technology in another body) if its noise characteristics are half of the 10D is these low light environments.

Also recheck the Luminance charts above (the ones you snipped out of your response). Bart |

Truth is, you don't know ****. It's a very P&S like DSLR in this regard. Even Phil's brilliantly lit (a bone thrown to his biggest cash cow) ISO 800 Canon 10D demo images are heinous... Uh-huh. Compared to your crappy Sigma, the Canon at ASA 800 *SMOKES* your pitiful Sigma. The 10D is also extrememly noisy at ISO 100, compared to Foveon. Especially considering you have to underexpose to avoid sharply blown highlites. But it is an average Bayer DSLR in terms of noise. While the even more ancient Canon 1Ds is a truly horrid performer with respect to noise, even for a Bayer, and even at ISO 100... Compared to a 10D at any speed, it's a wonder Sigma and Foveon are still in business. |
