Canon’s widest prime lens, the 14mm f2.8 L, is a beautiful specimen for ultra-wide landscape & interior photography.  Color and contrast are excellent, like all of the Canon L primes.  What's special about this lens vs. some of the other wide angle and fisheye lenses out there is that this is what's called a rectilinear corrected lens. This means that your photos will not have the typical fun-house mirror look like a fisheye.  That's what makes this lens ideal for architecture and landscape photography.

Being a version II, this lens is optically much better than the previous 14L version I.  One big thing to note about this lens, is the filter situation.  Due to the sexy front element popping out the front of the lens, it is not possible to use traditional screw on filters.  This lens is so wide that you almost don't need them.  The Canon 14mm will accept gelatin filters through a rear slot, but you’re on your own with those, we don’t stock them.  

Other uses for the Canon 14mm is in Steadicam/Glidecam and MoVI work.  Because of its ultra wide focal length the 14L has an incredibly short hyperfocal distance.  At f/2.8 anything that's beyond 3ft. away will be in focus.  Stop down to f/5.6 and that distance gets closer to 1 ft. Paired with a crop body camera, this is a great lens for stabilized flying shots.
