The Zeiss ZM 85mm f/2 Sonnar (about $3350) is an ultra high performance 85mm lens hand-built in Germany, and thus is one of the premium optics of the Zeiss ZM line.

Its low distortion and ultra-high imaging quality make it eminently suitable for true-to-life imagery.


Like all lenses over 50mm, your primary challenge on a rangefinder like the Leica M9 will be accurate focus and framing, just as with the Leica 75mm f/2 APO-Summicron-M. In essence, perfect 20/20 vision is needed, along with perfect rangefinder focus adjustment.

Leica M9/M7/M8 users should consider the Viewfinder Magnifier 1.4X for use with 75/85/90mm lenses.

Image quality

This lens offers very high performance, but please see the Guide to Leica for commentary.

A faint trace of pincushion distortion is all there is.

This is effectively zero distortion for any practical purpose, and much less distortion than the Leica offerings in the 75mm - 90mm range.
