Zeiss's autofocus 40mm f/2 for Sony FE — Close Focus design with 1:2 macro capability.
The ZEISS Batis 40mm f/2 CF was released in 2018 as the close-focus variant in the Sony FE Batis series, providing a 40mm standard perspective with 0.24m minimum focus distance and 1:3.3 magnification — a close-focus enhancement, not true macro. Nine elements in 8 groups. Nine rounded aperture blades. 67mm filter thread. At 361g. Linear motor autofocus. No OSS.
The optical design uses 9 elements in 8 groups (floating element design). Nine rounded aperture blades. The 67mm filter thread. At 361g the lens is moderate. Minimum focus distance of 0.24m; 1:3.3 magnification — close-focus capability, not 1:1 or 1:2 macro. Linear motor for fast, quiet AF. No OSS. f/2 maximum aperture. Full-frame coverage.
The CF (Close Focus) designation at 1:3.3 magnification provides close-subject framing for product, food, and detail photography from 24cm — useful without requiring a dedicated macro lens. The 40mm focal length provides a slightly narrower field than 35mm options while remaining in the normal/standard perspective range. The floating element corrects optical performance at close focus distances.
On the used market the ZEISS Batis 40mm f/2 CF is available at Batis series pricing. Condition checks: linear AF response, 67mm front element for marks. CF capability: 1:3.3 at 0.24m (not 1:2 or 1:1 — this is a close-focus prime, not a macro lens). No OSS. Compatible with all Sony FE-mount full-frame and APS-C bodies.
