|I bought one of those a couple years ago, at an actual camera shop, for too much money. I first put it on a SMC-A40-80 on my APS-C camera (K20D) and got a full-circle fisheye at ~40mm and a frame filling image from ~60mm onwards. I've since tried it on various other zooms in that range. I look forward to trying it on something like a 35-90 because the frame-filling projections get interesting at longer focal lengths.
But I've never been really happy with it. Its internal diaphragm needs to be stopped WAY down for any edge sharpness, which is never very good, at leas not on mine. I more recently bought an eBay bargain Precision Design Super AF Fisheye adapter (0.25x, 58mm thread) for US$20 shipped. I mount it on my DA18-55 or DA18-250 and get full-circle fisheye at ~18mm. More aberrations than the Kenko, but better edge detail.
Too many film+digi cams+lenses, oh my -- Pentax K20D, K-1000, M42s, more
