Customer reviews
Impressive, but watch out for that front element 
by .. K. Gittins (CA USA)
Sometimes you just need to go to the extreme - in this case it is really wide angle. In my old Canon film-camera days, I had the 15mm 2.8 fisheye which was an even bigger chunk of glass because of its speed.
Now that I have gone to the Pentax K100D camera, I was pleasantly surprised to see this 10-17mm lens was available. I was even happier because unlike the Canon lens, the Pentax is a zoom, so that not every shot has to be the distorted wide angle that you think of when you hear "fisheye". The lens goes out to the equivalent of about 26mm on a 35mm format, which is a very useful focal length as well.
The lens also allows manually tweaking the focus while in the auto-focus mode - something my 2 Sigma lenses warn against.
The only drawbacks to the lens that I see are that you can not mount a filter and the curved front element is exposed (same for the Canon). So, just use a little caution. And, unlike the old Canon, there are no rear filters either. Finally, for those who like to manually adjust the aperture ring - there isn't one. It's all set through the camera :-)
I could go on about the lens, but as they say, a picture is worth a thousand words, so I've posted a few photos in the Amazon collection.
Fun Lens to Have by .. Jehan Ghouse (Hebron, KY, USA)
Have owned this lens since December 2007 and have had a lot of fun with it. At 17mm, it functions like a conventional wide angle lens, but at 10mm it is truly a fish-eye. The flexibility cannot be beat! Image quality is excellent (color rendition and sharpness). It can produce some interesting perpectives once you learn how to exploit its characteristics.
The lens surface extends (bulges out) beyond the front rim of the lens which can expose it more than a conventional lens. However, Pentax claims that it has a special coating which is supposed to resist scratches. I am ultra careful and choose not to test the strenght of the coating!! The lens cap is a slip-on type vs. a clip-on type. The lens is a tad heavy, but solidy built.
The more I use this lens, the more pleased I am that I purchased it.
Rediscover the fun in photography with unique lenses by .. Nirudha Perera (Sri Lanka)
While most lens reviews focus and look down on lenses for distortion, sometimes it's just the thing to make unique photos. Take a fisheye to a family or sports event or on any trip and capture some great photos. Throw in some action and you can have a load of fun in the process!
While I haven't posted that many shots you can see some samples from this lens here

fish-eye Pentax 10-17mm by .. Richard Albeck (West Linn, Or, USA)
Talk about a fun lens. I am doing fun stuff again. Of course too many fish-eye shots are not well received in a wedding shoot but the option to shoot in tight surroundings like stairs, or group up the groomsmen and bridesmaids and add a little flair is great! I've found nothing wrong with this lens and it's fun to see people's reactions to the shots. After some Photoshop lens correction the shots are can also be acceptably distortion free. Once again Pentax provides the value for the money.
Impressive by .. B. Ober (Layton, UT)
I purchased this to play with both the wide angle capabilities and the fish-eye views this creates with my K10D. The pictures thus far (roughly 100-120) have shown excellent quality. The types of pictures I've been able to take by purchasing this have impressed me!
The only issue I have seen is the images are dark when the sun is in the picture - which is easy to do when the sun is high in the sky. At 180 degrees of view, it captures a lot. Like with anything, one simply needs to check the shot before taking the picture and use the right lens for the situation.
