With a 35mm equivalent focal length range of 288mm, this lens offers a Telephoto perspective.
*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
Portraits are best shot with focal lengths between 85 and 300mm depending on whether shooting mid-length or close-ups and the amount spacial compression wanted. Depth of field is the most important tool to manipulate and a fast lens will give more scope for creative treatment.
Fashion is difficult to define but requires focal lengths of between 28-200mm. Very often capturing movement, a fast focus ultrasonic lens is important.
Wildlife Scenic photography
Wider, more scenic wildlife shots need anything from 70-300mm in focal length depending on how close you are the particular scene. Singling out individual animals usually requires more powerful telephoto. In telephoto, camera-shake is more problematic and stabilization is very important. Fast ultrasonic focusing is important in capturing fleeting moments.
Fluorite and UD Lenses
Fluorite, which boasts a very low dispersion of light, is capable of combating the residual aberration that standard optical glass fails to eliminate. UD (Ultra Low Dispersion) lens elements incorporate low-dispersion optical glass which minimizes distortion and chromatic aberration.
Extending the focusing lens group at close focusing distances can sometimes cause distortions such as curvature of field – particularly noticeable with wide-angle lenses. Canon counteracts this problem by incorporating 'floating' lens elements into many EF lenses. Because the floating component is separate to the focusing lens group, aberrations caused by lens extensions are significantly reduced. This means you can be sure of high image quality at all focusing distances.
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.
