At a Glance

This telephoto zoom for full-frame Canon RF keeps a constant f/2.8 across 100-300 mm and has an optical stabilizer. At 2.59 kg it is heavy, but the wide aperture stays available throughout the range, and teleconverters can be attached. It suits sports, wildlife, events and portraits with shallow depth of field.

Worth knowing

  • At 2.6 kg it is heavy: a monopod or tripod helps for longer sessions.
  • Large 112 mm filter thread: screw-in filters are correspondingly large.
