This series evaluates performance of the Zeiss Otus 55mm f/1.4 APO-Distagon on a distance scene from f/1.4 through f/6.3. In dim flat light, 'penetrating power' is needed to deliver good contrast and micro contrast; the light here was very flat and diffuse.
Shot on the Nikon Z7 using the Nikon FTZ lens adapter. The Nikon Z7 has an ultra-thin sensor cover glass 1.1mm thick that may impact the imaging performance versus the Nikon D850 (~2.0 mm thick).
