Just pushing the 50D
Single 2 lamp 4 foot flourescent light using sp41 lamps and my cat relaxing in the garage. 1600 iso and minimal processing. Shot in RAW , I backed off the contrast from 0 to -3, color 0, sharp 3. Never went to noise reduction from the raw image in DPP. Just downsized converted jpeg in Picasa to 800X600. White balance was great considering the light source. I always had to correct using the Xti in my garage lights. Used 17-55 mm IS lens.
I really like this body combined with the 17-55 in traditionally bad light conditions. If you 40D guys are enjoying this clean iso, you have been holding back making that point across to me. It can take a while before some of this info sinks in
Canon EOS 50D,7D and some lens and equipment.
