What is the canon ef 200mm f 2 8l ii usm good for?
The Canon EF 200mm f/2.8L II USM is a fixed telephoto prime for full-frame Canon bodies. You can't zoom, so you choose your subject distance, and f/2.8 gives plenty of light and background blur.
It suits a few kinds of shooting:
- Portraits from a distance. A longer lens flatters faces, and at 200mm you can frame a headshot with room between you and your subject. See the portraits guide.
- Subjects you can't approach, such as sport, wildlife, or birds.
- Distant landscape details, like a lone tree or light on a far ridge. The landscape guide makes the case for telephoto work.
It isn't stabilised, so use a faster shutter speed when shooting handheld. If you want more range, the Canon EF 70-200mm f/2.8L IS II USM covers 70 to 200mm in one lens.
