Zeiss Batis 40mm f/2 CF Aperture Series: White Aspen, Late Dusk

Get Zeiss Batis at B&H Photo and see my Sony mirrorless wishlist.

This series assesses corner-to-corner sharpness, field curvature and any possible focus shift, particularly in corner areas, on the 42-megapixel Sony A7R III. On a scene like this, field curvature is a primary concern because even a small amount of it will drastically reduce sharpness where the field curves out of focus, typically in the mid zones or corners.

As a close focus (“CF”) lens which Zeiss states to be excellent from 1:5 all the way to infinity (“floating lens design for consistently high image quality across the entire focus range”), the far-distance performance is a good place to start to evaluate field curvature and total performance. The MTF charts for the Zeiss Batis 40mm f/2 CF show a very consistent performance across the field, which is consistent with the stated goal.
