What cameras fit the sigma 200mm f 2 dg os sports?
The Sigma 200mm f/2 DG OS Sports fits cameras with a Sony E or L-Mount. The list is long. Full-frame options include the Sony a7 IV, the Sony a1, the Panasonic Lumix S5 II and the Leica SL3. APS-C bodies such as the Sony a6700 and Sony a6400 also work.
This lens is made for full frame, so that's where it performs as marked. On APS-C it frames like 300mm, and f/2 gives about the depth of field of f/3. That reach is handy for sport, but if you're buying a body to go with it, I'd pick full frame.
For the complete list of compatible bodies, see the lens page.
