For Sony there are a few good 85mm options. After a lot of debate between the 85/1.4, 85/1.8, and the Sigma 85/1.4 Art, and trying them all out in store, I decided on the 85/1.8. The GM is an excellent lens, but as someone pointed out, it’s not 300% better than the 85/1.8, which it’s about 300% the price of. The Sigma is a great lens, but it’s a very heavy lens. If it were just being used in studio, on a tripod, then no problem, but for all purpose being out and about as well as in studio, the one I got was a great compromise, and one I’m very happy with.
