The EF 50mm f/1.2L USM is stunningly designed with dust and water droplet resistance structures for rugged outdoor operation. It is a peerless super fast standard lens featuring an ultra-large aperture for a narrow depth of field and the soft background blur so loved by photographers everywhere. The EF 50mm f/1.2L USM lens is suitable for any shooting situation; its lens coating and construction are optimised to minimise the ghosting and flare that frequently occurs when lenses are used with digital cameras. The high-performance, weather-resistant lens delivers all the superb image resolution and contrast one can expect in a Canon L Series lens.
