Canon EF70-300mm f 4.5-5.6 IS USM Specification

The Canon EF70-300mm f/4.5-5.6 IS USM lens is a versatile telephoto zoom lens designed for Canon's EF mount DSLR cameras. It offers a focal length range of 70-300mm, making it suitable for a variety of photography styles, including wildlife, sports, and portraiture. The lens features an aperture range of f/4.5-5.6, which allows for flexibility in various lighting conditions. One of its standout features is the Image Stabilization (IS) system, which provides up to three stops of shake correction, enabling sharper images when shooting handheld. The lens is equipped with a Micro Ultrasonic Motor (USM) for fast, smooth, and quiet autofocus, making it ideal for both still photography and video recording. It incorporates a 9-blade circular diaphragm, which contributes to a pleasing bokeh effect, enhancing the aesthetic quality of out-of-focus areas in an image. The optical construction comprises 15 elements in 10 groups, including one ultra-low dispersion (UD) element that helps to minimize chromatic aberrations and enhance image clarity. The lens also features a Super Spectra coating that reduces lens flare and ghosting, contributing to improved contrast and color fidelity. With a minimum focusing distance of 1.5 meters, the lens allows for relatively close-up shots at the telephoto end. The physical design includes a focus distance window and a zoom lock switch to prevent lens creep during transport. Weighing approximately 630 grams, the lens is relatively lightweight, making it convenient for extended shooting sessions. Its compatibility with both full-frame and APS-C sensor cameras further broadens its utility, providing an effective focal length range of 112-480mm on APS-C bodies.
