What is the sony e 18 55mm f 3 5 5 6 oss good for?
The Sony E 18-55mm f/3.5-5.6 OSS is a kit zoom, and it's a sensible everyday lens. It's made for APS-C cameras, and it's stabilised and autofocuses. On APS-C it frames roughly like 27-82mm on full frame, which covers wide scenes, street shots and close portraits.
The catch is the aperture. It gets darker as you zoom in, so you'll want more light at the long end. If that matters to you, read Lenses for how aperture affects exposure and background blur.
For an everyday kit, I'd pair it with one of these:
- Sony a6100, a simple APS-C body for learning on
- Sony a6400, if you want a more capable APS-C body
- Sony a6600, a step up in body
