Sigma 135mm f 1 4 dg art vs sony fe 135mm f 1 8 gm?

The Sigma is the brighter lens. Its f/1.4 aperture gives you more background blur and a shallower depth of field than the Sony's f/1.8, which matters most for tight portraits. The Sigma also mounts on L-Mount as well as Sony E, and it fits a much wider range of bodies, including Leica and Panasonic. The Sony is Sony E only, so it suits you if you're already on a Sony body and want the lens to match.

Both are full-frame primes at 135mm, both autofocus, and neither has stabilisation. On APS-C, the Sigma's f/1.4 gives about the depth of field of f/2.1, and the Sony's f/1.8 gives about f/2.7.

If you shoot people and want the most blur, go with the Sigma 135mm f/1.4 DG Art. For more on what 135mm does for faces, see portraits. The Sony FE 135mm f/1.8 GM is the choice if you want a Sony-only lens.
