I still have both Cameras and find the 7D far better than the 40D in this respect. Shooting RAW I was always very reluctant to go above ISO 400 on the 40D but have no problem in shooting at ISO 800 on the 7D. As has already been indicated by Tim the 7D is unforgiving if you under expose and then push in processing. Providing you get the exposure right (preferably exposing to the right) I much prefer the noise levels on the 7D, in fact I would say that ISO 800 on the 7D is as good if not better than ISO 400 on the 40D.Also the comment on about AI servo producing soft results is again strange to my experiences - I shoot in AI Servo 99% of the time and have no problems in getting sharp images. I can only assume that there are some rogue Cameras out there.The Stonechat shot below is typical of what I am getting at ISO 400 on the 7D, it is a very heavy crop with just a minimal amount of noise reduction on the BG (something I do with just about all my shot no matter what ISO).The bug , Spadger and Blackcap shots were at ISO 800, again with just minimal noise reduction on the BG. All three were very heavy crops.BTW all three bird shots were taken in AI servo mode (and all with a 2x tc).Might not be up to some peoples standards but they are sure better than I was achieving with the 40D.</blockquote>
