    Cons: Nothing !

    Pros: Sharp for this special type of lense :) Compact lense ! More than the Zoom kit 18-55 !

    Summary: First fisheye zoom on a 35mm camera ,a full-frame fisheye collector. Test on APS-C Pentax K5 and KS-1 = 24-42 mm

    Cons: starts from fullframe fisheye and ends like an overdistorted 28mm. It is not so useful for a fisheye to be a zoom.

    Pros: Good quality on film. Interesting lens and decent AF

    Summary: First fisheye zoom on a 35mm camera ever, a must fo a fisheye collector. Will be back and sought after when pentax will make a full frame DSLR
