What cameras fit the tamron sp af 28 75mm f 2 8 xr di ld aspherical if macro?
The Tamron SP AF 28-75mm f/2.8 XR Di LD Aspherical (IF) Macro is made for full frame sensors, and it fits a long list of bodies from three mounts: Canon EF, Nikon F and Pentax K. On a full frame body it frames as marked, 28-75mm.
It also works on APS-C, where it gives a tighter view. The full catalogue page lists every camera it fits, and the full frame picks are the ones to look at first:
If you shoot APS-C, the Canon EOS 80D, Nikon D7500 and Pentax KP are sensible matches. Check the sensor sizes page if you're unsure what your body uses, and the Tamron page has the full list.
