I have just received my 50D back from repair - something was wrong with the circuitry. Having got it back I was wondering if I should consider AF adjustment for my lenses. The handbook appears to offer a warning so I am a little wary. Hitherto I think focus has been OK but of course I do not know if it could be better, I was wondering if anyone has made adjustments and how it was done.
I guess you point at a high contrast target then go to Custom function 111 - 7 but then how do I know what adjustments should be made - does the camera indicate what I should dial in?
Any advice would be welcome, thanks
Jon
