Canon RF 600mm f/11 IS STM Lens

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.  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. Fixed f/11 aperture contributes to the sleek and portable form factor as well as a balanced mixture of depth of field and sharpness. Retractable/extendable design, with a locking lens barrel, offers an impressively compact form factor considering the super-telephoto design. STM stepping motor offers fast, quiet, smooth, and accurate autofocus performance that is ideal for video recording as well as still shooting. Compatible with optional Extender RF 1.4x and Extender RF 2x teleconverters to further increase the effective focal length.
