Sony fe 85mm f 1 4 gm vs samyang af 85mm f 1 4 fe ii?

On paper these two are the same lens. Both are 85mm f/1.4 primes for full frame, both fit Sony E, both have autofocus, and neither is stabilised. The site doesn't list prices or compare sharpness or build, so I can't tell you which one is better. Check current prices and reviews before you choose.

The Sony FE 85mm f/1.4 GM is the camera maker's own lens. The Samyang AF 85mm f/1.4 FE II is a third-party option, usually cheaper. If you go with the Samyang, make sure your body's autofocus works with it, as explained in third-party lenses. For how an 85mm works for portraits, see the lenses for portraits.
