Canon SLR EF-mount zoom lens

A Canon EF 100-300mm f/5.6L zoom lens

The
EF 100–300mm
refers to three telephoto zoom lenses produced past Canon. They are of the EF lens mount that is uniform with the EOS line of cameras.

The iii versions are:

  • f/v.6
  • f/5.6L
  • f/iv.5–5.6 USM

The 2 v.vi versions were contemporaries, launched at the start of the Canon EOS system. The L version had a different optical construction which improved sharpness, color, and chromatic aberrations. Otherwise the lenses were physically similar. Canon decided to upgrade the non-50 version in the early on 1990s to the iv.5-5.6 version, non the L. It had improved styling, a ring zoom command instead of push-pull, and a larger (faster) aperture at the wider end. It also fabricated use of a much faster and much quieter Ultrasonic (“USM”) motor for autofocus command, instead of the Arc-Form Bulldoze (“AFD”) found on the 5.half dozen lenses. The L version never received this upgrade, and information technology lasted long afterwards the v.6 non-Fifty had been discontinued. Following Canon practice, the L lens was sold including its lens hood and protective case.
