One of the most versatile focal lengths is now available for Canon RF mount, the Canon RF 70-200mm f/2.8L IS USM Lens is an L-series telephoto zoom distinguished by its bright design and advanced optics. Ideal for a variety of subjects ranging from portraiture to sports, the fast constant f/2.8 maximum aperture excels in difficult lighting conditions and also offers increased control over depth of field for isolating subjects.
The optical layout of 17 elements in 13 groups makes use of One Super UD and Four UD low dispersion glass elements to suppress chromatic aberrations and colour fringing in order to realize a high degree of clarity throughout the zoom range. Two asperical elements reduces distortion to ensure optimal image quality across the zoom range. 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.
