Zeiss 15mm f/2.8 Distagon: Field Curvature, MTF, Focus (Mosaic)
Added to Guide to Zeiss is a detailed study from f/2.8- f/16 using the Zeiss 15mm f/2.8 Distagon on the Nikon D800E showing how field curvature, MTF and choice of focus interact.
It’s not easy to show field curvature well, but this study turned out well, and it should be of some help to anyone shooting the 15/2.8 Distagon.
