Pentax SMC DA 10-17MM F3.5-4.5 ED (IF) FISH-EYE Pro Reviews

There's a lot to like about the Pentax 10-17mm ƒ/3.5-4.5 fisheye. You never have to worry about getting your landscape into the frame; on the contrary, I found that in use I had more of an issue trying to keep either the sun, or my shadow, out of the frame. Keeping the sun at bay turned out to be less important, as flare was better-controlled than I would have expected from a wide-angle lens. Pentax markets this lens as allowing the user to ''capture images with an expanded perspective including creative deformation...'' and it's true, I can see many possibilities with the fisheye lens that just aren't possible without extensive post-processing. Optically it's very good (at least, as much as our tests can measure) and the build quality measures up very nicely as well. The best part is that it's not prohibitively expensive, making a swim in the wide world of fisheyes a very easy possibility.
