An impressive and incredibly unique super-telephoto, the Canon RF 600mm f/11 IS STM Lens 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- {Key Features} - RF-Mount Lens/Full-Frame Format - Fixed f/11 Aperture - Retractable, Locking Lens Barrel - Gapless Dual-Layer Diffractive Optics {Box Contents} - Canon RF 600mm f/11 IS STM Lens - Canon E-82 II 82mm Lens Cap - Canon Lens Dust Cap RF
