Since I use primarily zeiss and converted leica r lenses with my Nikon D3/D3X bodies.....I am into Manual Focus. The new D3X seems to front focus 4-5CM at 2M .
If this was using AF, the camera calibration feature could be used to fine tune specific lenses ..but I believe the AF of the camera to be accurate. Non CPU lenses can not be adjusted?
Its my understanding that the AF system works completely independent of the focusing screen (off the sensor or a separate AF sensor?) But how does the FOCUS ASSIST that is helpful for MF lenses work?
The screen and the focus assist seem to agree exactly.
It would be very helpful if someone could confirm my understanding of the two focusing systems and how the FOCUS ASSIST works.
