Zeiss's autofocus 40mm f/2 for Sony FE — Close Focus design with 1:2 macro capability.
The ZEISS Batis 40mm f/2 CF launched in 2018 as a slightly-wider-than-standard prime for Sony FE mount with a headline feature — CF (Close Focus) capability reaching 1:2 half-macro magnification at 24cm minimum focus distance.
Optically excellent — sharp from f/2.8 with Zeiss T* coating providing outstanding flare control. The 1:2 macro capability transforms it from a standard prime into a versatile tool for both general and close-up photography. Autofocus using a linear motor — quiet and fast.
Sony FE mount with 67mm filter thread. Weighs 361g. Weather-sealed dust and moisture resistant. OLED display on barrel showing focus distance and DOF. Minimum focus distance 24cm with 1:2 magnification. De-clickable aperture for video.
Available used at mid-range to professional prices. The close-focus macro capability is the unique selling point. The Sony FE 35mm f/1.8 is lighter and cheaper for everyday use. The Batis line offers Zeiss optics with Sony FE autofocus — the best of both worlds.
