Best camera for the sigma 105mm f 1 4 dg hsm art?
For this lens I'd stay with full frame. It's a large, heavy portrait prime, and on APS-C it frames like about 158mm (or 168mm on Canon), which is more reach than most portrait work needs. Full frame gives you the 105mm view the lens is built for, and its shallow depth of field is the reason to buy it.
Three full-frame bodies from the list that pair well with it:
- Sony a7 III: a well-rounded full-frame body on Sony E.
- Nikon D750: a full-frame DSLR option on Nikon F.
- Canon EOS 5D Mark IV: the one to pick if you shoot Canon EF.
If you're still deciding how the lens will be used, read the portrait lens guide before you commit. For the lens itself, see the Sigma 105mm f/1.4 page.
