Sigma 50mm f 1 4 dg dn art vs sony planar t fe 50mm f 1 4 za?

Both are 50mm f/1.4 autofocus primes for full-frame cameras, with no stabilisation, and they frame and sit at the same depth of field. The real difference is mounts. The Sigma 50mm f/1.4 DG DN Art comes in Sony E and L-Mount, so it also fits Leica SL and Panasonic Lumix S bodies. The Sony Planar T\* FE 50mm f/1.4 ZA is Sony E only.

If you shoot Sony and plan to stay there, either lens does the job, so choose on price and how each one feels in your hand. If you might switch to Leica or Panasonic later, the Sigma keeps that door open. If you want a faster option, Sigma also makes a 50mm f/1.2. For more on why a prime like these is worth having, see primes or zooms.
