A Lightweight Telephoto Zoom for Sports, Portraits, and Wildlife
The Canon EF 75-300mm f/4-5.6 III Lens is a compact, budget-friendly telephoto zoom designed for Canon EF-mount DSLRs, built for photographers who want extended reach for sports, portraits, and wildlife without the size, weight, or cost of a professional-grade zoom. With a versatile 4x zoom range, this lens covers everything from flattering portrait compression at the short end to genuine wildlife-capable reach at 300mm.
Designed for Portability and Everyday Telephoto Use
This lens is made for photographers who need telephoto reach in a manageable, easy-to-carry package. Measuring 4.8 inches long and 2.8 inches in diameter, and weighing just under a pound, it's the lightest 4x telephoto zoom in its class, making it easy to bring along without committing to a dedicated bag slot. Its 4.9-foot minimum focusing distance allows for close-detail work on flowers, insects, and small subjects, extending its usefulness well beyond distant subjects alone.
Optical Performance and Build
The optical design features 13 elements in 9 groups, with a front-group rotating extension system for zooming. A Super Spectra coating is applied to individual elements to reduce lens flare and ghosting, helping maintain high contrast and accurate colors in bright or backlit conditions, while a seven-blade diaphragm produces smooth, pleasing background blur.
Fast, DC Motor-Driven Autofocus
The lens uses a DC micro motor to drive autofocus, delivering fast and accurate focusing performance well-suited to a range of subjects, from portraits to sports and casual wildlife photography. It's compatible across the entire Canon EOS EF body lineup, and can also be adapted for use on Canon RF, Sony E, or Fujifilm X mirrorless systems.
