Best camera for the sony fe 300mm f 2 8 gm oss?
The 300mm f/2.8 is a full-frame lens, so I'd start with a full-frame body. My pick for most people is the Sony a7 IV. It's a sensible all-rounder that gives you the lens's full 300mm reach, and it's easier to live with than a flagship.
If you want the top body for fast action, look at the Sony a1. It's the one I'd choose if money isn't the main concern.
If you'd rather have more reach for less, the Sony a6700 is an APS-C body. On it, this lens frames like about 450mm on full frame, and f/2.8 gives the depth of field of about f/4.2. That makes it a good fit for distant wildlife or sport.
For the full list of bodies this lens fits, see the lens page.
