The Canon RF 600mm f/11 IS STM is a uniquely compact and lightweight super-telephoto prime lens designed for full-frame Canon RF-mount mirrorless cameras, making handheld telephoto shooting more accessible than ever. Its fixed f/11 aperture and retractable design contribute to its sleek, portable profile, while gapless dual-layer diffractive optics minimize chromatic and spherical aberrations for sharp, high-quality images. An Optical Image Stabilizer provides up to five stops of shake reduction, enhancing performance in low-light conditions and at slower shutter speeds. The STM stepping motor delivers fast, quiet, and precise autofocus, ideal for both stills and video. Additional features include a customizable Control Ring for adjusting exposure settings and compatibility with RF 1.4x and 2x teleconverters to extend the lens's reach even further.
