An impressive and incredibly unique super-telephoto, the Canon RF 600mm f/11 IS STM is an especially compact and lightweight lens considering its long focal length. Featuring a retractable design and a fixed f/11 aperture, this lens\'s sleek profile makes handheld super-tele shooting a very real possibility, and optical image stabilization further helps to achieve sharp imagery when working in difficult lighting conditions. Also contributing to the reduced size is a distinct optical layout, which uses gapless dual-layer diffractive optics instead of multiple heavier individual elements, which also effectively controls color fringing and chromatic aberrations for high clarity. Complementing this design is an STM stepping motor that delivers quick and quiet autofocus performance that is suitable for both stills and video needs. Additionally, a Control Ring is also integrated into the lens design for intuitive control over exposure settings from the lens itself. If you need more reach, the 600mm is compatible with the 1.4x and 2x RF Extenders for an effective focal length of 840mm or 1200mm, respectively.

Super-telephoto prime is designed for use with full-frame Canon RF-mount mirrorless digital cameras.

Fixed f/11 aperture contributes to the sleek and portable form factor as well as a balanced mixture of depth of field and sharpness.

Gapless dual-layer diffractive optics contribute to a marked reduction in chromatic and spherical aberrations as well as benefit the design of a relatively compact and lightweight lens.

Retractable/extendable design, with a locking lens barrel, offers an impressively compact form factor considering the super-telephoto design.

An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to five stops to better enable working in low-light conditions and with slower shutter speeds.

STM stepping motor offers fast, quiet, smooth, and accurate autofocus performance that is ideal for video recording as well as still shooting.

Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.

Compatible with optional Extender RF 1.4x and Extender RF 2x teleconverters to further increase the effective focal length.
