Very nice Vincent! Some people think this camera sucks at high ISO. This is not the case here. I'm glad you like it.

Ya, what's funny is that when I was looking at coming from my 5d2 to a 1ds3, I looked a lot at ISO because I spend so much time at high ISOs. I heard from MANY people that the 5d2 is better. And I heard from a number of people that the 1ds3, 1ds2, and 5dc were all pretty close (just that the 1ds3 had a little advantage at a common print size, but was basically equal at the pixel level).
After extensive testing between the 1ds3 and my 5d2, I can not declare a champ there. The only advantage the 5d2 seems to have is in it's jpeg processing, which offers more NR options, and better jpeg NR. In raw, they are different, but I couldn't say there was any big difference either way (both good). In jpeg, the 5d2 take a little little lead at 3200, but the 1ds3 noise at 3200 is not very offensive.
Lastly, a good friend just picked up a 5dc (I had one a few years ago), and I've been spending some time using it. After getting used to the 1ds3, the 2 things that have shocked me is 1. how SLOW the 5dc is (even 5d2 feels sluggish after the 1ds) 2. the 1ds3 high-iso is a large improvement both at pixel level, and even more at common print/viewing sizes.
I think the 1ds3 iso is very good. Wouldn't mind if it was better though, but I haven't taken a picture yet with this body that was ruined by noise.
I describe the noise as 'honest and unoffensive, even pleasant at times', and I'd take that over 'smooth but fake/unnatural/over processed'
Although, the 1Ds III does have better ISO performance from 100-400 imho.
. M9 is next on my list, just picked up a minty M3. Are you going to post your work on rangefinders forum as you create it?







. It seems perfectly focus
