What is the sirui sniper 75mm f 1 2 good for?

The Sirui Sniper 75mm f/1.2 is a fast telephoto-style prime for APS-C cameras. On Sony E, Fujifilm X, or Nikon Z bodies it frames like about 112mm on full frame, and f/1.2 gives roughly the depth of field of f/1.8 there. That makes it a strong choice for portraits, tight headshots, and close-up work in low light, where you want a soft background and some distance between you and your subject. It's autofocus but not stabilised, so keep your shutter speed up.

On full-frame Sony and Nikon bodies it works in APS-C crop mode, at fewer megapixels. For the reasoning behind longer lenses for faces, see Portraits, and for the crop-factor maths, see the Focal length converter.
