What is the meike 33mm f 1 4 stm good for?
The Meike 33mm f/1.4 STM is a fast standard prime for APS-C cameras. On Sony E, Fujifilm X and Nikon Z APS-C bodies it frames roughly like a 50mm on full frame, and f/1.4 gives about the depth of field of f/2.1 there. That makes it a good match for low light, people, food and everyday street shots, where you want a soft background and a natural view.
It's autofocus but not stabilised, so keep your shutter speed up in dim rooms. It also fits many full-frame Sony and Nikon bodies, but only in APS-C crop mode, so you give up some resolution there.
If you want a fast standard prime for people, the Portraits guide explains why a 35mm-class lens works well for environmental portraits. For a first lens on APS-C, the Lenses guide suggests a fast standard prime alongside a standard zoom.
