Zeiss ZM 35mm f/1.4 Distagon

MTF for Zeiss ZM 35/1.4 Distagon

Contrast at f/1.4 is very high and exceptionally uniform across the field and with tightly controlled astigmatism, outperforming the famed Leica 35/1.4 Summilux-M ASPH in all three areas (ditto for the 35/2 Summicron-M ASPH). It also far outperforms the Zeiss ZM 35mm f/2 Biogon.

The f/1.4 performances represents the best (consistently high and uniform) performance one can ask for with any f/1.4 lens for Leica M.

Stopping down to f/4 raises contrast of coarse and fine structures to outstanding levels across the field, showing slightly higher overall values than the Leica Summilux 35/1.4 and with more uniformity*. It is an outstanding performer that looks to be the new champion for image quality at 35mm. Stopping down to f/5.6 adds depth of field, which is of particular benefit to the mid zones in the sense of sharpness in the nominal plane of focus.
