What cameras fit the sony fe 50mm f 1 4 gm?
The Sony FE 50mm f/1.4 GM fits a long run of Sony E-mount bodies, both full frame and APS-C. On full frame it frames as a straight 50mm. On APS-C it frames like 75mm, which many portrait shooters like.
The full frame bodies include the Sony a7 IV, the Sony a7R V and the Sony a1. On APS-C, the Sony a6700 and the Sony ZV-E10 II are good matches.
My pick is the a7 IV. It's a sensible full frame body, and this lens is at its best with that wider view. If you already own an APS-C body, the a6700 is the easiest way to get the 75mm look. The full list is on the Sony FE 50mm f/1.4 GM page, and the focal length converter shows how a 50mm lens changes across sensor sizes.
