    • Turn the lens until it stops, then detach it.
  2. Detach the lens from the adapter.

    • Attach lens caps to the lens you removed.

Caution

  • For lens precautions, see Detaching a Lens.
  • With lenses heavier than the camera, hold the camera by the lens when you shoot or carry it.
  • With EF lenses that incorporate a tripod mount (such as super telephoto lenses), attach the tripod to the tripod mount on the lens. When using lenses without a tripod mount, attach the tripod to the tripod mount on the mount adapter.
