Canon 50mm F1.4 EF USM

With its fast maximum aperture and rapid focusing system, the compact, high performance EF 50mm f1.4 USM standard lens can be relied on for superb performance in any field of photography. Fast f1.4 aperture Standard 46° angle of view USM focus motor with full-time manual focus override 45cm closest focusing distance Aspherical lens element 58mm filter size 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 f1.4. The lens is ideal for photographing landscapes and travel scenes as well as portraits and reportage. Ultrasonic focusing A 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 colour balance and enhance contrast. They also reduce flare and ghosting – a common problem caused by light bouncing off a camera's sensor.
