Canon EF 24mm f/1.4L II USM

The EF 24mm f/1.4L II USM incorporates the newest in Canon lens technology for spectacular sharpness and impressive performance at all settings. It features two high-precision, large-diameter aspherical lenses for sharpness across the sensor, even in peripheral areas of full-frame sensors. Lens elements have a newly-designed anti-reflective SWC (Sub Wavelength Coating) that departs from conventional coatings by using an extremely fine structure that minimizes ghosting and flaring across the lens surface, regardless of the angle with which light enters or exits. It also features two UD lens elements to minimize chromatic aberrations, incorporates rear-focusing, ultrasonic, quiet and high-speed AF with full-time manual override. A circular aperture provides beautiful out-of-focus detail and offers legendary dust- and water-resistant L-series construction using only lead-free glass.

The Digital Picture.com Says:

The Canon EF 24mm f/1.4 L II USM Lens is, without question, Canon's best-performing (optically and physically) and best-built 24mm autofocus lens. It is also Canon's widest angle lens with an aperture wider than f/2.8 - a full 2 stops wider than all wider angle Canon lenses. This lens looks great, feels great and functions superbly.

Canon Website Customer Review:

Since I purchased this lens about 4 months ago it has been fixed to my 30D. It took me a while to get used to utilizing the 1.4 f-stop because of how little depth of field you have to play with, but, if done right, the effects are amazing.
