Upload & Sell: On
Disregarding the focusing issues (which, I might add, are valid for some people), it was the image quality that ultimately proved to be the 7D's downfall for me. The blue channel showed it most obviously, but overall noise for 100 ISO was higher than on any other DSLR I've owned. I've only had a short time with the 5D MkII after selling the 7D two weeks ago, but I was pleasantly surprised to find that ISO 800 seems pretty similar to the 7D's 100 ISO. Overall file quality is significantly better with the 5D MkII, including shadow banding which could be atrocious with the 7D (feel free to call it operator error, but I think there should be some latitude in a file to open the shadows a bit in some circumstances). I personally hate the softening effects of NR, and could not find a way to process a 7D file that would hold up in very large prints, even compared to the lowly 1Ds (whose file quality at low ISOs I'm still enamored with, in some respects).
Everyone's mileage varies, and calling people out as incompetent when they may truly have hardware issues is a bit narrow-minded.
