Let us know if you see any difference. I'll call Canon next week…
Well, the camera is back in my hands. Its been raining all day so I can't really test. I did check the sensor and it is quite clean except for whatl ooks like a small fliud spot at right at the edge of the sensor. All of my setting were the same as when I sent the camera in, except date, time and frame number.
Checking the microadjust on all my lenses found them all still very close. I did change a few, one or two points, but that could have just been user error from the last adjustment.
Visually the autofocus seems superb, and the few snaps I took around the house were spot on. I'll test more tomorrow when the weather clears.
