Canon RF 70-200mm f/2.8 L IS USM Lens
Constant f/2.8 Aperture
- Bright f/2.8 constant maximum aperture maintains consistent illumination throughout the zoom range and suits working in low-light conditions as well as affords increased control over depth of field for working with selective focus techniques.
- Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
- The front and rear elements feature a protective Fluorine coating to resist fingerprints and smudges and to make cleaning significantly easier.
Advanced Optical Design
- One UD (Ultra-Low Dispersion) element and one Super UD element help to minimize chromatic aberrations and color fringing in order to provide greater clarity and color accuracy.
- Two aspherical elements are used to correct spherical aberrations and distortion for improved sharpness and accurate rendering.
- An Air Sphere Coating (ASC) has been applied to lens elements to reduce backlit flaring and ghosting for maintained light transmission and high contrast in strong lighting conditions.
Dual Nano USM AF System
- Dual Nano USM system utilizes both a ring type USM and an STM mechanism to realize quick and accurate focusing.
- Smooth and nearly silent autofocus suits both photography and video applications.
- Full-time manual focus control available when working in the one-shot AF mode.
Optical Image Stabilization
- An Optical Image Stabilizer helps to minimize the appearance of camera shake by five stops.
