Canon RF 15-35mm f/2.8L IS USM Lens

Covering a versatile wide-angle focal length range, the RF 15-35mm f/2.8L IS USM from Canon is also characterized by its bright f/2.8 constant maximum aperture. This bright design enables working in available light conditions and also affords greater control over depth of field. The range of wide focal lengths suits working in a variety of situations, from landscape to documentary shooting, and this zoom is complemented by an advanced optical design that greatly reduces color fringing and distortion for high clarity and sharpness. An Air-Sphere coating has also been applied to reduce flare and ghosting for improved contrast and color fidelity when working in bright conditions.

Complementing the imaging capabilities is an apt 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 15-35mm is weather-sealed and has a fluorine coating to protect the front and rear elements.

• Standard wide-angle to telephoto zoom lens is designed for use with full-frame Canon RF-mount mirrorless cameras.
• 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.
• Three UD (Ultra-Low Dispersion) elements help to minimize chromatic aberrations and color fringing in order to provide greater clarity and color accuracy.
• Three 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.
• An Optical Image Stabilizer helps to minimize the appearance of camera shake by five stops to better enable working in low-light conditions and with slower shutter speeds.
• Nano USM system utilizes both a ring type USM and an STM mechanism to realize quick and accurate focusing that is also smooth and nearly silent to suit both photography and video applications.
• Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
