"EF Mount Lens Aperture Range: f/1.4-22 Two High Refraction Lens Elements Gaussian Optics Eliminate Astigmatism Ultrasonic Autofocus Motor Manual Focus Override Infrared Index Minimum Focus Distance: 17.8" Filter Thread Diameter: 58mm 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, and a one-year warranty.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.

An affordable L-series ultra-wide-angle zoom lens that's ideal for both film and digital SLRs. Superior optics are assured by the use of three aspherical lens elements, in addition to a Super UD (Ultra-low Dispersion) glass element. Optical coatings are optimized for use with digital cameras. This lens focuses as close as 11 inches (0.28m), and offers both Canon's full-time manual focus and a powerful ring-type USM for fast and silent AF. It has a constant f/4 maximum aperture, and offers the choice of screw-in 77mm filters or a holder in the rear of the lens for up to three gel filters. Finally, it offers weather-resistant construction similar to other high-end L-series lenses.
