Recommended Applications

*Recommendations are based only on the features necessary to perform the application successfully and do not take into account the relative image quality of different lenses

Field-based sports

300-400mm focal lengths produce scenic shots in field sports played in stadiums. Action close-ups require 500-600mm lenses. Fast ultrasonic focus is a must to quickly capture movement. Tripod mounting is recommended.

Technologies

UD Lenses

UD (Ultra Low Dispersion) lens elements incorporate low-dispersion optical glass which minimizes distortion and chromatic aberration.

Inner and Rear Focusing System

Many photographic lenses use either all-group focusing (all lens groups are moved together along the optical axis) or front-group focusing (only the front lens group is moved). These systems require far more power from the drive mechanism, limiting auto focus speeds. The need for large front lens groups also limits the potential for compact lens sizes.

Full-Time Manual Focus

Many EF lenses are equipped with a ring-type USM which allows full-time manual focus in AF mode. This means you can manually fine-tune focusing as soon as auto focus is complete, without having to switch to manual focusing mode. Full-time manual focusing on most compatible lenses uses a mechanical system for instant responsiveness.

Full-time manual focus is also possible on some lenses equipped with a Micro USM, such as the EF 50mm f/1.4 USM.

Ultrasonic Motor (USM)

Canon's Ultrasonic Motor (USM) is a lens-based motor to harness ultrasonic oscillation energy. This technology makes focusing precise, virtually noiseless and incredibly quick – some lenses focusing literally faster than the human eye. The USM starts instantaneously and stops the moment focus is achieved, with no overshooting. What's more, the USM requires minimal battery power so you can shoot for longer on a single charge.
