Canon EF 100-300mm lens

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

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

The three versions are:

f/5.6
f/5.6L
f/4.5–5.6 USM

The two 5.6 versions were contemporaries, launched at the beginning 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-L version in the early 1990s to the 4.5-5.6 version, not the L. It had improved styling, a ring zoom control instead of push-pull, and a larger (faster) aperture at the wider end. It also made use of a much faster and much quieter Ultrasonic ("USM") motor for autofocus control, instead of the Arc-Form Drive ("AFD") found on the 5.6 lenses. The L version never received this upgrade, and it lasted long after the 5.6 non-L had been discontinued. Following Canon practice, the L lens was sold including its lens hood and protective case.
