Canon RF 100-500mm f/4.5-7.1L IS USM Lens

The Canon RF 100-500mm f/4.5-7.1L IS USM spans a short- to super-telephoto range within a sleek and portable form factor. The modest maximum aperture enables a relatively portable design that is well-suited to handheld, walkaround use and optical image stabilization also helps to steady photos and videos by up to five stops when working in difficult lighting conditions. Balancing the distinguished optical assets is the Dual Nano USM focus system, which delivers fast, nearly silent autofocus performance with full-time manual focus override. A unique Control Ring is also integrated into the lens design for intuitive control over exposure settings from the lens itself and the rotating zoom ring also feature torque adjustment for fine-tuning the feel of the lens. Six UD (Ultra-Low Dispersion) elements and one Super UD element help to minimize chromatic aberrations and color fringing in order to provide greater clarity and color accuracy. Three distinct IS modes are available: standard single-shot mode, a panning-optimized mode, and a mode that only activates the Image Stabilizer during the exposure. This focusing system also affords full-time manual focus control when working in the one-shot AF mode. A protective fluorine coating has been applied to the front and rear elements to resist fingerprints and smudges and to make cleaning these elements significantly easier. Rotation-type zoom ring features torque adjustment capabilities to fine-tune the handling of the lens or to prevent the lens from accidentally extending.
