Description — Canon RF 100-500mm f/4.5-7.1 L IS USM
The Canon 100-500mm f/4.5-7.1 L IS USM is a full-frame telephoto zoom lens built natively for the Canon RF mirrorless mount. Its focal length range spans 100mm to 500mm, covering everything from moderate telephoto compression to serious long-reach shooting. The variable maximum aperture of f/4.5 at 100mm and f/7.1 at 500mm is central to understanding its exposure characteristics at different zoom positions. Optical image stabilization is integrated into the optical design to help manage camera shake, particularly relevant at the longer end of the zoom range.
The 77mm filter thread keeps filter compatibility practical and affordable, aligning with a broadly available filter size. Weighing 1370g, the lens is a substantial piece of kit that rewards a considered approach to support and carrying. Autofocus and manual focus are both supported, providing operational flexibility.
As a Zoom type lens with a Full Frame format, it is designed to pair with Canon's RF mirrorless ecosystem without compromise.
