I primarily shoot birds and my main body is the 7D used with the 400 f/5.6L. I am thinking of picking up a 7D mk2. So, my main concern is with all things being equal, will upgrading to the mk 2 with my 400 f/5.6L produce for me shots with a noticeably improved IQ over the 7D and the 400 f/5.6L?
I would love to see your bird images taken with the 7D mk2 and the 400 f/5.6L Thank you.
