Tokina 10-17mm f/3.5-4.5 ATX Pro DX Fisheye Lens
The fact that this fisheye is a zoom allows the user to adjust just how exaggerated the fisheye effect is. At the maximum 17mm, this lens is an ultra wide angle, but at the lowest 10mm it's a nice fisheye. The zoom means that the lens isn't as fast as other lenses in the same price range, but it's still an excellent option, particularly when the versatility of a zoom is welcomed. The zoom gets you an angle of view from about 180 degrees to 100. This lens also has nice macro capabilities, with a 5.5 inch minimum focusing distance. Overall, this Tokina is an excellent choice.
