The deeper I get into the quality of the Zeiss 55mm Otus, the more I continue to be impressed. Here is a single shot of a cultivated grape leaf taken with the Nikon D810 and the Zeiss Otus 55mm at ISO 64, f/16, and 1/13 sec. Also included is a 100% crop of part of the leaf edge, so you can see the remarkable clarity of this Zeiss lens.
