Canon EF 15mm f/2.8 Fisheye
(From Canon lens literature) Fisheye lens with a 180º angle of view for unique and intriguing effects. The wide depth of field makes it even more interesting. The short minimum focusing distance of 8 in. (20 cm) gives new meaning to close-up shots. The lens has a fixed petal-type hood and a gelatin filter holder at the rear.

I bought this lens as ultra wide for my Canon 40D and when I upgraded to 5D and 1D Mk III I rediscovered the lens once again. The only non-L lens in my bag.reviewed October 4th, 2009 (purchased for $620)

My copy of this excellent lens is sharp wide open in center and sharp from corner to corner at 5.6.reviewed December 23rd, 2007 (purchased for $616)
The only con is a very noisy AF when compared to USM.

I have this and the 14mm f2.8 L. I prefer this lens. At least in my case, this lens is sharper and has better flare control. (Although my 14 focuses a little faster.) Fisheyes are cool but you should use them sparingly, like once per assignment or maybe just once a month or every couple of months. The look can get tedious pretty quickly. That said, in the right hands this is a really fun, useful lens. On the 1.6 crop bodies this is a useful lens - it crops out most of the Fisheye effect and gives you a kind of interesting wide angle look. jackreviewed December 8th, 2006 (purchased for $350)
7 out of 10 points and recommended by cold_fire (5 reviews)sharp stopped down, small, light, good build qualitya bit soft wide open, CAs at image borders, the cap always tends to come off in the bag, loud AF actuator
I'm using it on a 1.3 crop factor body and, although the sharpness remains rather consistent across the frame, CAs almost ruin the picture at the edges and never vanish even at f22. Perspective is really wild and most of the times brings lots of smiles.reviewed November 7th, 2006 (purchased for $500)
Should not be used for more than one picture a mount as the FE effect tends to lose it's appeal when used often.
