What is the canon ef 16 35mm f 2 8l iii usm good for?

The Canon EF 16-35mm f/2.8L III USM is a wide zoom for full-frame bodies, so it suits big skies, strong foregrounds and interiors. On full frame it covers exactly 16-35mm. It has autofocus but no stabilisation.

For landscapes I'd be honest about the f/2.8. You'll usually shoot at f/8 to f/11 anyway, so you're paying for speed you won't use. An f/4 wide zoom is lighter and cheaper, as the Landscape guide notes.

It fits full-frame bodies such as the Canon EOS 5D Mark IV and Canon EOS 6D Mark II. On an APS-C body like the Canon EOS 80D it frames roughly like 26-56mm, which is less wide than most landscape work wants.
