Canon EF 50mm f/1.4 USM Standard & Medium Telephoto Lens for Canon SLR Cameras - Fixed International Version

The 50mm f/ 1.4 standard lens is a terrific choice for both casual and professional photographers. The lens is outfitted with two high-refraction lens elements and new Gaussian optics, which combine to eliminate astigmatism and suppress astigmatic difference. As a result, the lens obtains crisp images with little flare even at the maximum aperture. The lens's f/ 1.4 speed, meanwhile, is perfect for available-light shooting. And as a bonus, this lens is the only lens in the EF system to offer an extra-small Micro Ultra Sonic Motor (USM) while still providing a full-time manual focusing option.

Other features include a close focusing distance of 1.5 feet, a 58mm filter size. what's in the boxCanon Normal EF 50mm f/ 1.4 USM Autofocus Lens, E-58U 58mm Snap-On Lens Cap, Lens Dust Cap E (Rear) and 1-Year warranty.
