60D focus error...
I just shot some fairly close cat pictures with my Sigma 50mm f1.4 @ f2, and they're consistently in focus on his nose, but I had focused on the eye. I just shot a test with a page of lined paper and got a similar result - sharp focus in front of the actual point of focus. This is the first time I've questioned the AF accuracy of the camera, but I'm not usually up close at f2, as I was today.
This is fixable, I hope? I assume I'll be sending the camera back to Canon. Do these AF systems need to be tweaked for each specific lens?
The issue is most likely not the camera, but, the lens.
Sigma lenses are known for having calibration issues.
The good news is that Sigma will calibrate it for free under waranty, and since it is an EX lens the warranty is 4 years (you'll need a copy of your receipt or invoice).
I recently sent in a lens for calibration. Turn around was one week from the day they received it, till the day I got it back. My only cost was packing, shipping and insurance.
