The Canon EF 50mm f/1.2L USM lens is a peerless standard lens for Canon digital SLR cameras. The lens is suitable for any shooting situation, with a lens coating and construction type that are optimized to minimize the ghosting and flare that frequently occurs when lenses are used with digital cameras. The lens also offers an ultra-large aperture that produces a narrow depth of field and the type of soft background blur so loved by photographers everywhere. The high-performance, weather-resistant lens delivers all the superb image resolution and contrast you expect in a Canon L Series lens.
