Get Zeiss Touit 50mm at B&H Photo.
When I first glanced at this series, I was not that that interested in presenting it.
But I took a closer look, and quickly decided that it was an excellent demonstration of outstanding performance right down to f/16—an important aperture for shooting close-range work (depth of field).
Includes HD and UltraHD images along with crops, all over the f/2.8 to f/16 aperture range. Shot on the Sony A7R in APS-C crop mode (4800 X 3200 images).
