Reviewed: Kolarivision-Modified Sony A7R II with Zeiss Batis 25mm f/2 Distagon

Get Sony A7R II mirrorless and Leica 28mm f/1.4 Summilux-M ASPH B&H Photo.

Zeiss Batis 25mm f/2 Distagon

A specially modified Sony A7R II (KolariVision) and a stock unmodified A7R II were used to explore the performance of the Zeiss Batis 25mm f/2 Distagon.

Following the three lens survey of Leica M lenses on the KolariVision-mod A7R II, a key question is whether modifying the Sony A7R II to deliver better performance with Leica M lenses also modifies (degrades) the performance of native lenses which expect the appropriate thickness and refractive-index sensor cover glass.

The answer speaks directly to whether a modified Sony A7R II is suitable as an all-arounder, or whether shooters might need both an unmodified camera (for native lenses and/or DSLR lenses) and a modified camera (for Leica M and Zeiss ZM rangefinder lenses).
