Used Canon EF 300mm f/4 L IS Lens

The Used Canon EF 300mm f/4L IS USM Lens is a high-performance Canon L-series super-telephoto prime lens designed for photographers who need long reach, excellent optical performance and fast, responsive autofocus. With its fixed 300mm focal length, bright f/4 maximum aperture and built-in Image Stabiliser, this lens is an excellent choice for wildlife, bird photography, sports, action, nature and outdoor photography.

The 300mm focal length provides substantial reach for filling the frame with distant subjects, while the f/4 maximum aperture allows good subject separation and attractive background blur. The built-in 2-stop Image Stabiliser helps reduce the effects of camera shake, making handheld photography more practical, particularly in lower-light conditions. The IS system also features two selectable modes, including a mode designed for tracking moving subjects.

As part of Canon's professional L-series, the EF 300mm f/4L IS USM combines a robust, portable design with advanced optical and focusing technology. Its ring-type USM autofocus motor provides fast and quiet AF operation, with full-time manual focus override available. Canon's optical specifications include 15 elements in 11 groups, an 8-blade diaphragm and a minimum focusing distance of approximately 1.5 metres, giving this lens useful flexibility for closer wildlife and sports subjects.
