Best camera for the sigma 135mm f 1 4 dg art?
The Sigma 135mm f/1.4 DG Art is a full-frame lens, so I'd pair it with a full-frame body. Any of the Sony E-mount full-frame cameras listed on the lens page will work well.
- Sony a7 IV is my everyday pick: a sensible all-rounder for portraits and general shooting.
- Sony a7R V if you want the most detail for tight headshots and crops.
- Sony a9 III if you shoot fast action, such as sport or performers.
On an APS-C body like the Sony a6700, it becomes a 202mm-equivalent lens, which is a very specialised setup. For portrait framing, see Portraits.
