Take a look at a more detailed look into the Canon EF 75-300mm f/4-5.6 III USM
Lightweight telephoto zoom with USM
The lightest 4x telephoto zoom lens in its class. Ideal for photographing sports, portraiture, wildlife etc. The lens’ telephoto effect compresses perspective and restricts depth of field, effectively blurring backgrounds. At the 300mm focal length it is possbile to fill the frame with a postcard from a distance of 1.5 meters.
Fully Electronic Lens Mount
An integrated AF motor provides fast autofocusing performance. The lens’ electromagnetic diaphragm ensures incredibly accurate control over aperture positioning.
Super Spectra coating
Super Spectra coatings ensure accurate colour balance and enhance contrast. They also reduce flare and ghosting – a common problem caused by light bouncing off a camera’s sensor.
A ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting.
