Best camera for the tamron sp af 28 75mm f 2 8 xr di ld aspherical if macro?
The Tamron 28-75mm f/2.8 is a full frame lens, so I'd pair it with a full frame body and let it cover its full range as marked. Three picks from its list:
- Nikon D750 is a solid all-round full frame body if you shoot Nikon F.
- Canon EOS 6D Mark II gives you full frame on Canon without the bulk.
- Pentax K-1 Mark II is the full frame choice if you're in the Pentax K system.
If you already own an APS-C body such as the Canon EOS 80D, the lens still works, but it becomes a tighter, roughly 45-120mm equivalent. The focal length converter explains that shift in more detail.
