Description — Canon EF 600mm f/4L IS USM
The Canon EF 600mm f/4L IS USM is a prime super telephoto lens with a fixed 600mm focal length and a maximum aperture of f/4, mounted on the Canon EF system for full-frame coverage. Built for DSLR camera systems, it supports both autofocus and manual focus operation, allowing photographers to switch between focusing modes as the situation demands. Optical image stabilization is included to help counteract camera movement at this demanding focal length. The lens accepts filters via a 52mm thread, which on a lens of this type is typically implemented as a drop-in or rear-mount system.
At 5,370g, it is a physically demanding lens that will generally require dedicated support hardware during use. As a Canon L-series super telephoto prime, it represents a focused tool for photographers who need substantial reach and a wide maximum aperture in a single, fixed-focal-length package.
