Fast maximum aperture and rapid focusing set the Canon EF 50mm apart from the herd. Versatile enough for just about any type of photography, it's an essential part of any Canon DSLR user's setup. Key benefits: Advanced Gaussian optics and two high-refraction lens elements let you capture crisp, clean images, even wide open at F/1.4. The lens is ideal for photographing landscapes and travel scenes as well as portraits. An ultrasonic motor (USM) powers rapid - near silent - autofocus. Full manual override is available, making it possible to adjust focus without leaving AF mode. The circular aperture gives out of focus regions a softer feel making foreground objects stand out against a smoother, blurred background. Super Spectra coating keeps colour balance vibrant and accurate, while reducing unwanted flare and ghosting for sharper images than ever. For use with EF mount Canon DSLR cameras
