What are the alternatives to the zeiss batis 135mm f 2 8?
The Batis 135mm f/2.8 is a light, stabilised telephoto prime for portraits and detail, so its alternatives are lenses that do the same job. My portraits guide points to two. An 85mm f/1.8 is the classic full-frame portrait lens, with a more comfortable working distance and a softer background. A 70-200mm f/2.8 zoom covers the 135mm range and more, which helps if you also shoot events or sport.
If you're on a budget, a 50mm f/1.8 is the cheapest great lens for people, though it gives a less compressed look.
The lens page only lists the cameras it fits, so for specific models, browse the Sony E mount listings and compare them against the focal length guide.
