American Photo's editors choose the top ten camera lenses from 2006.
Since it's designed for the smaller-than-35mm image sensor in Pentax D-SLRs, this unique fisheye can get by with a smaller image circle-and with reduced size, weight, and cost. Yet with zooming: At 10mm it delivers the 180 degrees you'd expect from a full-frame fisheye, but zoom to 17mm and you get a less curvy 100 degrees. Closest focusing is 5.5 inches-a good thing, since you'll want to get really close. About $400.
