v This strange lens offers the distorted view of a fisheye lens, with the convenience of a zoom lens. It offers a 180degree field of view, from corner to corner when set at 10mm and the equivalent of a 25.5mm lens on a 35mm camera, with lots of barrel distortion, at 17mm.

Great lens for close quarters. More than sharp enough for landscapes and interior shots as long as the main subjects are near the center of the frame. Corners can be a bit soft but not terribly so. For the price it is a welcome addition to my Pentax lineup.

Nice compact wide angle to fisheye lens. Great for candid shots in tight crowded situations, parties, street photography etc. Also enables one to be creative in landscape photos. Interesting night photography effects.

tac sharp & an overall great lens for all sorts of occasions. great for really big landscapes & tight up close shots. 10mm has all sorts of cool distortion, if you're into that. I tend to use the 17mm more, it comes in very handy.

    solidly built, it has a hefty feel to it

    the outside lens is really curved & protrudes from the main lens body., I havent scratched the lens, but it concerns me to see the glass hanging out :o), keep that lens cap on between shots
