Product Description Offering versatility and long reach in a notably sleek form factor, the Canon RF 70-200mm f/2.8L IS USM is a flexible telephoto zoom characterized by its bright design and advanced optics. The constant f/2.8 maximum aperture suits working in difficult lighting conditions and also enables greater control over depth of field. A sophisticated optical design comprises a series of specialized elements, which help to suppress a variety of aberrations throughout the zoom range for well-controlled imagery. An Air Sphere Coating has also been applied to suppress flare and ghosting when working in strong 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. An Image Stabilizer also compensates for up to five stops of camera shake to help produce sharper handheld shots in difficult lighting conditions. A unique Control Ring is also integrated into the lens design for intuitive control over exposure settings from the lens itself. Additionally, this 70-200mm is weather-sealed and has a fluorine coating to protect the front and rear elements.
