Canon 7D vs 40D/more pixels on the subject
Hello Everyone,
I have read all the posts regarding FF vs crop sensors and have learned much from the great discussions thus far. My question might be redundant, but I will throw this out just to confirm my decision to upgrade to the 7D from my 40D, which I have had since 2008. Obviously, I will gain more resolution from the jump from 10.1 MP to 18MP. Also the 100% viewfinder on the 7D should help my aging eyes see more detail on the subject. Oh, and the AF system is superior, as well as the faster frame rate. Correct so far? Now here is the second part of the question: if I understand the numerous explanations provided by Arash, if I cannot get close enough to fill the frame with a bird-I should take my 600mm (300 f2.8 + 2X III) off of the 5D MKII, and put it on the 7D, assuming I have enough light to keep the ISO down. BTW, what is the optimal ISO for the least amount of noise on the 7D, assuming the image is exposed correctly?
Thanks in advance to anyone who wants to comment. :S3:
