Panasonic lumix s pro 50mm f 1 4 vs sigma 50mm f 1 4 dg dn art?

Both are 50mm f/1.4 autofocus primes for full frame, and neither has stabilisation. On full frame they frame as 50mm, and on APS-C they frame like 75mm. The real difference is mount. The Panasonic Lumix S Pro 50mm f/1.4 is L-Mount only, so it suits Panasonic Lumix S, Leica SL and Sigma fp bodies. The Sigma 50mm f/1.4 DG DN Art works on both Sony E and L-Mount, so if you shoot Sony, it's the one for you.

If you already shoot L-Mount, either will do, so choose based on the bodies you own. Before buying a non-maker lens, check the third-party lens advice. For why a 50mm is a good first prime for people, see the portraits guide.
