Canon EF 24mm f/1.4L USM
(From Canon lens literature) Professional wide-angle lens with an ultra-large maximum aperture of f/1.4. This is the first EF lens to employ both a replicated Aspherical lens element to suppress distortion and spherical aberration, and a UD lens element to correct lateral chromatic aberration. Thanks to the floating construction, excellent corner-to-corner delineation is attained from 10 in. (25 cm) to infinity.

I had the opportunity to try this lens when looking for a fast normal prime for my 350D (Rebel XT).reviewed December 5th, 2006
I didn't intend to buy it because of the price, but also because using it on a crop body was paying the price and weight for a very fast wide angle lens, whereas I would use it like a ~40mm, that should be light, cheap and easy to design...
Basically, I've been really impressed by the L build quality and feeling.
The contrast and colors were really great, sharpness was just good at 1.4 but got much better past f:2
This lens really makes sense on a full frame body and is not really exciting on a crop body, but the cropped part I saw was realy good...
