Description — Canon EF 500mm f/4L IS II USM
The Canon EF 500mm f/4L IS II USM is a prime super telephoto lens designed for the Canon EF mount, offering full-frame coverage at a fixed focal length of 500mm. The maximum aperture of f/4 provides solid light-gathering performance at extreme distances, making it a serious tool when reach and speed matter together. Optical image stabilization is built into the lens, providing a meaningful advantage when shooting in lower light or at slower shutter speeds. Focus options include both autofocus and manual focus, ensuring versatility across a wide range of shooting conditions.
The front element accepts 52mm filters — a practical specification given the lens's size class. Tipping the scales at 3,190g, this lens demands respect in terms of physical handling; a monopod or tripod will be the standard companion in the field. As a dedicated Canon EF-mount DSLR lens, it integrates natively with Canon's full-frame and APS-C EF-mount bodies.
For photographers who need a committed 500mm prime with a fast f/4 aperture and built-in optical stabilization, this lens delivers a focused, no-compromise specification set.
