I recently purchase a 6d from canon refurb sale. Tested it out, image quality sucked. AF was totally off, even after focal and hand AFMA. I compared shots taken from a bh demo unit, with no edited settings besides raw. Immediately noticeably better. I prepare a whole folder for canon repair to look at.
The choice was to send it back or have them fix it. I've need a replacement for my junked 7d I sold a while ago. I chose to fix it. Jus got it back, took some shots, then focal. Here are the results.
Minimal info on the repair sheet - AF adjustments.
These are twice as good as the blur city it was originally. But it doesn't look great, especially not full frame great. Admittedly, the pictures do look a lot better and it harder to argue it, but look at those results...like soft. To less soft. In comparison, before it went back the settings came back -9 -9 for this sharp copy of 24-105.
I will not an do not conduct image quality test after image processing, so no I won't be running them through lightroom or dpp to see how much better they can get. I expect good images out of camera.
Lastly, every image I work with is viewed at 100 percent and similar settings, so there is no deviation.
What do you guys think? More details to come.
