        Comments about Rokinon 8mm Ultra Wide Angle f/3.5 Fisheye Lens for Pentax K Mount:

        I find this one of the better fish-eyes on the market, although there are not many uses for fish-eye lenses, when one is needed this is definitely good to have, especially at the price. The lens is built extremely well, made out of metal, and it's quite rugged. The only thing I dislike about this lens is that it does not auto focus,although that's not a big issue since it's quite easy to manual focus with this lens. All in all definitely a worthwhile piece of glass to purchase.

            For the price I got an very nice lens. Image are sharp, even on the edges. AR caoting is very efficient, what seems to be very important, as, most a the time, you'll have the sun in the field of view.

            Comments about Rokinon 8mm Ultra Wide Angle f/3.5 Fisheye Lens for Pentax K Mount:

            I shoot both stills and HDSLR through my Pentax bodies and am thrilled to have added this Ultra Wide angle lens to my bag. I have ogled, oohed and ahhed fisheyes for years but always thought their typically high prices would keep me from ever springing for one. I caught this Rokinon at a great sales price and it works splendidly with both my K30 and K01 bodies. We shoot product reviews and love the "mind bending" photos that this lens generates. The lack of autofocus is not a deal breaker, as others have commented.

            Excellent fisheye for the money

              Comments about Rokinon 8mm Ultra Wide Angle f/3.5 Fisheye Lens for Pentax K Mount:

              This fisheye is great for the money. It produces sharp images with a very wide field of view. If you are worried about the fisheye look you can practice shooting a scene in such a way that it isn't drastically apparent or you can get software such as fisheye-hemi to correct the lens distortion.

              The only con about this lens that I can really think of is that the focus is usually not set properly (for unknown reasons) from the factory and you have to loosen three small screws under the rubber focus ring and calibrate it, but you can find tutorials on this and it's little more than a five minute job that you have to do only one time.

                Comments about Rokinon 8mm Ultra Wide Angle f/3.5 Fisheye Lens for Pentax K Mount:

                I use this lens for street photography and 'creative' stuff. This lens is both cheap and excellent. It has little chromatic aberration which is not bad at all for a fisheye! It's manually focused but you can use hyperfocal and don't worry about it at all (at f/3.5, focusing at 1.3 meters will give you a depth of field from .5 meters to infinity). This is a no brainer, I don't see why I wouldn't recommend this lens to anybody who wants to give fisheye lenses a try...

                      loves the 180° view, however i wish it that it had more then 8mm zoom but it is still a great lens for the price
