CANON EF 85mm f/1.4L IS USM

Canon EF 85mm f/1.4 L IS USM Objective

Distinguished by its rapid design and is capabilities, the EF 85 mm f/1.4 L is USM by Canon is a first short telephoto lens very suitable for portrait applications. As a L-series lens, it is characterized by a sophisticated optical design that includes a glass-molded aspheric element to greatly reduce spherical aberrations and distortion to improve sharpness and clarity. Individual elements also feature an Air Sphere coating (ASC) to suppress lens reflection and phantom effect for greater contrast and color fidelity in backlight situations.
As a complement to optical attributes, this lens also incorporates a four-stop optical image stabilization system that minimizes the appearance of camera vibration for a crisper shot on the handheld. A ring-type ultrasonic motor (USM) also offers fast and accurate self-focus performance, along with a full-time manual focus override for precise control. In addition, as with all L-series lenses, this 85 mm f/1.4 has a dust-and weather-resistant construction, as well as a fluoride coating on exposed elements, to benefit its use in adverse environmental conditions.
The main portrait length is designed for Canon full frame EF Digital SLR, however, it can also be used with APS-C models where it will provide an equivalent focal distance of 136 mm.
Notably, the maximum aperture of f/1.4 offers ample depth-of-field control to work with selective focus techniques. This brilliant design also benefits from working in low-light conditions.
A glass-molded aspheric element helps reduce distortion and spherical aberrations to improve sharpness and clarity.
An Air Sphere coating (ASC) was applied to the lens elements to reduce widening and retroilluminated phantom effect for sustained light transmission and high contrast in intense lighting conditions.
An ultrasonic ring-type (USM) engine, coupled with optimized focus algorithms and a high-speed CPU, is used to deliver fast, accurate, and quiet auto-focus performance as well as a manual override of the full-time approach.
Optical image stabilization minimizes the effects of camera movement by compensating for up to four shutter speed stops.
The rounded nine-leaf diaphragm contributes to a pleasant approach 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 to work in adverse environmental conditions.
The fluoride coating on the exposed elements protects the optical system, resists stains and fingerprints and is easier to clean.
