What are the alternatives to the samyang af 85mm f 1 4 fe ii?
If you want an 85mm for portraits, the closest alternatives I cover are the other Samyang FE II primes. The Samyang AF 50mm f/1.4 FE II and the Samyang AF 35mm f/1.4 FE II are both fast full-frame primes, but they give you a wider view than the 85.
For the same portrait job, my portraits guide is the place to look. It recommends an 85mm f/1.8 as the classic full-frame portrait lens, with soft backgrounds and a comfortable working distance. If you need even more reach for tight headshots, it also suggests a 135mm or 70-200mm f/2.8.
