What is the sony fe 70 200mm f 4 macro g oss ii good for?
The Sony FE 70-200mm f/4 Macro G OSS II is a telephoto zoom with image stabilisation and autofocus, made for full-frame cameras. On full frame it covers 70-200mm as marked. On APS-C it gives roughly the view of 105-300mm.
It suits sport and larger animals from the sideline, where 70-200mm is a sensible start. It also works for portraits with a bit of distance, since standing back flatters faces and keeps the background soft. And telephoto landscapes pick out layers of hills and distant light.
The f/4 maximum aperture keeps it lighter than f/2.8 versions. You'll want good light or a higher ISO in dim venues. It's a solid all-rounder on a Sony a7 III or any other full-frame body in the Sony E range.
