Achieve stunning photos with this compact, high performance EF 50mm f/1.4 USM lens. With its fast maximum aperture and focusing system, this lens delivers superb performance in any field of photography – and the lightweight design means it’s easy to carry everywhere. Delivering first-rate optics with two high-refraction lens elements, you’ll get ultra sharp and clear cut images, even at f/1.4. The Ultra Sonic Motor (USM) motor drives autofocus extremely quickly and quietly, with excellent holding torque ensuring the point of focus is reached accurately. There is full-time manual override too, allowing you to adjust the focus without leaving the autofocus mode. A circular 8-bladed aperture diaphragm gives out-of-focus regions a softer look, letting sharp foreground objects stand out against elegant bokeh.
