What is the canon ef s 18 55mm f 3 5 5 6 is ii good for?
The Canon EF-S 18-55mm f/3.5-5.6 IS II is a sensible everyday kit zoom for an APS-C Canon. It covers wide to standard, roughly 29-88mm in full-frame terms, which suits travel, family and general snapshots. It's stabilised and has autofocus, so it's forgiving handheld. The catch is the aperture: at f/3.5-5.6 it gets darker as you zoom in, so don't expect much background blur or strong low-light performance.
It only works on APS-C bodies, so keep it away from full-frame Canons. It fits a long list of EOS cameras, including the Canon EOS 80D, the Canon EOS 850D and the Canon EOS 2000D.
To see how its framing will suit what you shoot, try the Focal length converter.
