Description — Canon 70-300mm f/4-5.6 IS USM
The Canon EF 70-300mm f/4-5.6 IS USM is a telephoto zoom lens designed for Canon EF-mount DSLR cameras. With a focal length range spanning 70mm to 300mm, it delivers meaningful reach for subjects at distance. The lens is built to full-frame standards, ensuring it can be used across Canon's range of full-frame and APS-C DSLR bodies without vignetting concerns on the former.
A variable maximum aperture of f/4 at 70mm transitioning to f/5.6 at 300mm is standard for this class of telephoto zoom. Optical image stabilization is integrated into the lens, a valuable asset when shooting handheld at longer focal lengths. The lens supports both autofocus and manual focus, giving photographers control over how they acquire and track subjects. Accessories are straightforward to add thanks to the 58mm filter thread at the front.
