Zeiss ZM Lenses on Leica M Digital
Just added to my Guide to Leica is a new page showing focusing error with the Zeiss ZM 35/2 Biogon vs the Leica 35/1.4 Summilux-M ASPH FLE.
The findings are generally applicable to all Zeiss ZM lenses, and should be read by any Leica M9 / M9P / M Monochrom shooter. Also, the findings are even more relevant to those few who will be getting the M Monochrom, which will be unforgiving of focus error due to its exquisitely sharp sensor.
