Is the canon ef 200mm f 2 8l ii usm good on aps c?
Yes, it's a strong choice on APS-C if you want reach. On a Canon APS-C body it frames like 320mm on full frame, and f/2.8 gives about the depth of field of f/4.5. That suits birds, sport, and distant wildlife.
It isn't stabilised, so use a fast shutter speed or a tripod. These APS-C bodies from the catalogue all fit it:
- Canon EOS 7D Mark II: my pick for fast action.
- Canon EOS 90D: a capable body for telephoto work.
- Canon EOS 80D: a sensible all-rounder if you also shoot everyday subjects.
For the reasoning behind long lenses, see Portraits, which explains why longer focal lengths flatter faces.
