Frequently asked questions
Does the Zeiss Planar 85mm F1.4 ZA cover full frame?
Yes. It is a full-frame lens, and on APS-C A-mount bodies it frames like roughly a 128mm lens.
Does the Planar 85mm f/1.4 ZA have its own focus motor?
No. It uses the screw-drive motor in the camera body, so you need an A-mount body with that drive for autofocus.
How does it compare to the Sony 85mm f/2.8 SAM?
The f/1.4 Zeiss gives much shallower depth of field and a larger, heavier body at about 640 g. The 85mm f/2.8 SAM weighs only about 175 g and uses a lens-mounted SAM motor.
