    How do you get confirmation when you're in MF mode? Do you mean your lens is in AF mode but you focus manually, and then when you think you've got it you press your shutter halfway (or press the AF button if your cam is setup that way)?

    Push the AF-ON button (or half-press shutter) while the lens is in MF mode and the focus confirmation will light up.

    Hehe...okay - thought I was missing something there. So it's only "confirmation" if the camera agrees with you, otherwise it's AF... (lol)

    Having just used the AF micro-adjustment to calibrate my lenses, both of which were quite far out, I can't imagine me ever being more accurate than AF.


    Even 1 or 2 microadjustment points can make the difference between a pin-sharp and slightly soft image at wide apertures. Not only is it only possible to see that difference on a big screen (or magnified on the 5DII's screen) and IMO impossible to see through the viewfinder (with an AF screen), but even 10 microadjustment points (on a scale that goes from -20 to +20) is the equivalent of the tiniest movement of the MF ring. I just can't see me manual focusing with anywhere near that level of precision.
