Image Stabiliser lenses. Camera shake can ruin the most carefully composed photographs. Although the tripod is an

obvious and effective remedy, it is also a bulky and cumbersome solution. Canon solved this problem by developing the

world’s first SLR lenses with built-in Image Stabilisers. A compensatory optical system works in parallel to eliminate camera

shake. The result is equivalent to using a four times faster shutter speed and ensures focal precision in every single shot.

Ultra Sonic Motor (USM) lenses. USM lenses are both quick and quiet, making them ideal for taking photographs

of nervous creatures (and aggressive ones, if you are a member of the paparazzi). The innovative lens-based motor makes

EF lenses almost silent in operation and greatly speeds up the autofocusing process. Both compact and telephoto lenses

are made more effective and efficient with USM technology.

Professional lenses. The collection of EF telephoto lenses are characterised by their hallmark white bodies. They’re

a familiar sight at major sporting events and other occasions that attract widespread media interest. To capture the action

from the other end of the stadium (or from across town) you need a super telephoto lens which allows a faster shutter

speed and delivers perfect sharpness and contrast every time. These lenses greatly surpass the capacity of the human eye,

giving you exceptional results every time.

EF LENS SYSTEM

To get the best results from your Canon EOS camera, you need to fit Canon’s renowned EF

lenses. These lenses were specifically designed to maximise the performance of the camera

bodies. Each lens has its own dedicated focusing motor, which guarantees optimum speed and

accuracy. Two-way digital communication between electronic mounts, that are unique to the

Canon system, link camera and body. These ensure optimum photographic performance every

time. Internal microcomputers contain crucial operating data to guarantee a consistently smooth

all-round camera operation.

The EF lens range is constantly being refined and improved, to give the serious photographer

an enhanced professional edge and the professional photographer a touch of excellence.
