Subject: [Leica] RF vs SLR Sharpness

Sharpness or focusing accuracy?

Sharpness. 1962 Modern Photo test found mirror slap did effect image quality
in tests of a Nikon F. Mirror systems have improved since then but there is
still measurable impact.

RF Accuracy. Osterloch (sp) Leica M book has an excellent illustration of
superior focusing accuracy of Leica RF vs Leica R.

RF is  far far more accurate up to about 120mm or so.

More accurate focusing leads to sharper images...
