Canon EF 50mm f/1.4 USM Lens

Standard lens featuring superb quality and portability. Two high-refraction lens elements and Gaussian optics eliminate astigmatism and suppress astigmatic difference. Crisp images with little flare are obtained even at the maximum aperture. • Two high-refraction lens elements • 50mm focal length • 1:1.4 maximum aperture • 46 degree diagonal angle of view • 0.45m / 1.5 ft. closest focusing distance Versatile, compact standard-lens design Gaussian optics, combined with two high-refraction lens elements allow photographers working in all fields to 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 and reportage. Ultrasonic focusing An ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode. Smooth background blur A virtually circular aperture diaphragm gives out of focus regions a softer, more uniform feel. Sharp foreground objects stand out against a smooth blurred background. Super Spectra coating Super Spectra coatings ensure accurate color balance and enhance contrast. They also reduce flare and ghosting - a common problem caused by light bouncing off a camera's sensor.
