The Canon EF 75-300mm f/4-5.6 III USM is a lightweight telephoto zoom lens designed for shooting distant subjects with portability in mind.

Advantages

This lens is the lightest 4x telephoto zoom in its class, making it easy to carry for extended outdoor sessions. Its 75–300 mm focal range provides flexibility for sports, wildlife and portraiture, while the telephoto compression helps isolate subjects and produce pleasing background blur. At 300 mm the lens can tightly frame a small subject from a relatively short distance, expanding creative framing options.

How to use

Mount the lens on a Canon EF-compatible camera body and set the focal length between 75 and 300 mm to suit your subject distance. Use longer focal lengths to compress the scene and blur the background for portraits or wildlife. For sharper results, use a fast enough shutter speed to counteract camera shake at longer focal lengths or stabilize the camera with a monopod or tripod. Use the lens' focus controls to achieve accurate focus on moving subjects.

Usage recommendations

For best results in wildlife and sports shooting, combine the lens with a camera body that has good autofocus performance and use steady support or image-stabilization-equipped bodies when possible; keep in mind the lens's aperture range when choosing exposure settings in low light.
