Canon EF 75-300mm f/4-5.6 III Lens
Budget Telephoto Zoom – 4x Zoom Range, Super Spectra Coating & Compact Lightweight Design

The Canon EF 75-300mm f/4-5.6 III is a compact, lightweight 4x telephoto zoom lens designed for full-frame and APS-C format Canon EF-mount DSLRs (delivering an extended 120-480mm equivalent focal length range on APS-C sensors). Spanning portrait to medium telephoto perspectives, this entry-level telephoto optic is tailored for sports, outdoor wildlife, action, and portrait photography.

Optically, individual lens elements feature Canon’s Super Spectra Coating to minimize internal reflections, lens flare, and ghosting, maintaining contrast and neutral color rendition under bright lighting. Autofocus performance is driven by a DC micro motor paired with an electromagnetic diaphragm system to complement continuous burst shooting. Additional physical features include a 7-blade circular diaphragm for smooth background blur and an accessible lightweight barrel profile for handheld travel.
