Canon EF 85mm f/1.4L IS USM Lens

• Portrait-length prime is designed for full-frame Canon EF-mount DSLRs, however, can also be used with APS-C models where it will provide a 136mm equivalent focal length.
• Notably fast f/1.4 maximum aperture offers extensive control over depth of field for working with selective focus techniques. This bright design also benefits working in low-light conditions.
• One glass-molded aspherical element helps to reduce distortion and spherical aberrations for improved sharpness and clarity.
• 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.
• A ring-type Ultrasonic Motor (USM), along with optimized focusing algorithms and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
• Optical image stabilization minimizes the effects of camera shake by compensating for up to four stops of shutter speed.
• The rounded nine-blade diaphragm contributes to a pleasing out-of-focus quality that benefits the use of shallow depth of field and selective focus techniques.
• As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.
• Fluorine-coating on exposed elements affords protection to the optical system, resists smudging and fingerprints, and is easier to clean.
