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.

Fisheye lenses are never really perfect performers. However, these are special effect lenses where sheer quality is more a secondary aspect anyway. The Pentax SMC DA 10-17mm f/3.5-4.5 ED[IF] Fisheye is certainly sharp enough for its purpose and the high degree of barrel distortion is naturally a...

Just got this long awaited present-for-myself and have been putting it to good use in the two weeks since it arrived. Very very cool lens with very interesting results. The zoom range Although only 7 mm arithmetically, actually bears quite different composition structure at either end of this range...

I bought this lens for the super wide angle but also for the fisheye capability. I haven't ben able to us it much at home but hope to make good use on an up coming trip. I have gotten some really decent shots though at full wide angle for some really decent results not possible with a regular lens.

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

This is a really fun lens to use. I bought this to add to the wider angle spectrum of my lens collection. 10-17mm is a perfect focal length, as it creates a super wide-angle field of view, but does not completely distort your photo like a fisheye does.

Although I have not yet put this lens through a thorough test, I have found it on first use to be a tac-sharp (especially at f/8 and greater) and very fine lens for super wide angle shots. I hope to give a more detail analysis after I use it in my future travels.

Outstanding close focus ability, and a fine color rendition! There is also a very sturdy luxury feel to this lens. Useful for both macro photography and general wide angle shots. Sharp enough to later correct in post, if you prefer a more rectilinear look.

Expensive for the quality. At Lowest 10mm on the edges see lot of curvature / distortion. Not worth the 50k I paid for this.

If you have the money, you will like the lens for occasional use.... Great for making rooms look large if you are an estate agent and for making people look very strange... Auto focus is a bit noisy though....

Good basic wide angle lens.
