Playing around with a 15mm fisheye. It's a really fun lens, but just don't over use it...in other words, don't shoot your whole family vacation with it.

However, fisheyes don't necessarily need to look fishy by selecting the proper placement of the horizon line. The photo below was also taken with the 15mm fisheye lens. You can still see distortion in the lamp post on the right but it doesn't look too fishy.
