What cameras fit the tamron sp 45mm f 1 8 di vc usd?
The Tamron SP 45mm f/1.8 Di VC USD is a stabilised prime for Canon EF and Nikon F mounts, and it fits a long list of bodies. On full frame it frames exactly as marked, at 45mm. Good everyday full-frame picks are the Nikon D750 and the Canon EOS 6D Mark II.
If you want to keep the budget down, APS-C bodies work too, such as the Canon EOS 80D and the Nikon D7500. The lens frames tighter there, around 72mm on Canon and 68mm on Nikon.
Keep in mind that this is a DSLR-mount lens. If you're starting out and want a mirrorless body, Your first camera explains why that's usually the better route.
