The Canon EF 85mm f/1.4L IS USM Lens is a short telephoto prime that is distinguished by its fast design and IS capabilities. As an L-series lens, it features a sophisticated optical layout that includes one glass-molded aspherical element to greatly reduce spherical aberrations and distortion for improved sharpness and clarity. The individual elements also feature an Air Sphere Coating (ASC) to suppress lens flare and ghosting for greater contrast and color fidelity in backlit situations.
This lens also incorporates a four stop-effective optical image stabilization system that minimizes the appearance of camera shake for even sharper handheld shooting. A ring-type Ultrasonic Motor (USM) also affords quick and accurate autofocus performance, along with full frame manual focus override for fine-tuned control. Additionally, the 85mm features a dust and weather resistant construction, as well as a fluorine coating on exposed elements, to benefit its use in harsh environmental conditions.
