Re: DotTune: Video Tutorial for AF tuning without photographs

Is it possible that there is significant difference in accuracy of the focuspoints at diffent focal lenghts? I used dottune to fine tune my 35/1.4 at a little under 2 meters. If I shoot something at 2meters, focus seems fine. However, when shooting somthing at 4 or more meters, the focus seems to be far off?
