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. 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. 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.
