Issues with the quality of the 7D images have been popping up. Here is some interesting info on that subject. Seems that importing with Adobe raw is causing the problem according to this source. I don’t know enough, nor have I experimented any, to confirm of deny. I am going to check it out when I can tho.
Adobe Camera Raw 5.6 Official Release is a Noisy Mess for Canon 7D Raw Files!
On another note, I just ordered a Zagg protector for the 7D screen. I’ll let ya know how that works out.
