Comments about Sigma 8-16mm f/4.5-5.6 DC HSM Ultra-Wide Zoom Lens for Pentax Digital SLR:
This is lens is at it's sharpest at 8mm with a bith a softness in the extreme corner, mostly due to the effect a lens this wide have on the perspective.Stopping down decrease sharpness in the middle boost it in the corners. At f8 everything is mostly equal in terms of sharpness. There is some distortion a 8mm but it's easily correctable in lightroom . When zooming a little the distortion disapear. You can't use a filter with this lens because of the bulb like front element but the built in lens hood kind of protects it. You need to be careful so that you don't take your feet in the picture (yeah it's that wide).

A UW lens is a must for travel IMHO and this one is a great performer. I was pleased by it's size--fits a bag nicely--and, while it's not particularly fast, it really does the job in decent light.

If you like ultrawides and know how to use them this is a great addition to your lens bag. Nothing wider exist for APS-C. Light falloff is just as expected for such a wide lens. Sharp, some barrel distortion under 12mm and some pincushion above 12mm. Great size but that is also expected for APS-C only lenses.

Comments about Sigma 8-16mm f/4.5-5.6 DC HSM Ultra-Wide Zoom Lens for Pentax Digital SLR:
The lens comes up to an equivalent of 12-24 mm (full frame) on Pentax Cameras, which fit exactly what I needed.
It's been great using it so far - Good for landscapes, wedding imagery, architecture and interiors, but if you're indoors it's better to use a tripod rather than push the ISO.
Also pretty good for group shots on the less-wide side, as people have been complaining they appear too small when it's set too wide.
That's something to think about, as the lens isn't like a fisheye - Instead of bloating up, subjects become longer and "smaller" towards the middle.
Which brings me to...
Distortion: People/Objects appear extremely fat or distorted on the edges. It's not generally a problem if you understand your gear. Only obvious at the wider end.
All in all, a very well made lens.

Comments about Sigma 8-16mm f/4.5-5.6 DC HSM Ultra-Wide Zoom Lens for Pentax Digital SLR:
I needed to get just a few more degrees of field vision and the Sigma 8-16mm did the4 trick. I use it for indoor shots where I want to capture an entire space. It also works wonders for architecture.

Comments about Sigma 8-16mm f/4.5-5.6 DC HSM Ultra-Wide Zoom Lens for Pentax Digital SLR:
I have a Sigma 10-20 since moving to DSLR. I like the ultra wide angle to give me exaggerated perspective. When the Sigma 8-16 was announced, I have been eyeing it but thought the extreme focal length would make it difficult to optimize the optics. However, every review I read suggests that it has stellar IQ. The bubble fish eye front element may be the reason.
Bought this lens just last week. Based on careful but not chart based comparison with the Sigma 10-20, I can confirm that the 8-16 is better. Edge sharpness is significantly better at overlapping focal lengths and aperture values. Contrast is also visibly better. I have no difficulty in using the 8mm FL but it is indeed wide; you will be overwhelm by the FOV if you are not familiar with ultra wide angle.
I am very happy with this purchase since it expands an area that I have a big interest. Now onto the not so great items. The most obvious is the front element. It is like the eye of a bubble fish. The lens hood kind of protects it, but it is something I have to be very careful. Next is the inability to use filters because of the front element. Then the slow max aperture. The Sigma 10-20 f/4-5.6 is already slow, the 8-16 is even slower.
While I like wide angle, I don't like fish eye. So it is the only 8mm ultra wide angle in the market for K mount cameras. I have 6 Pentax lenses, 6 Sigmas and 2 Tamrons. So I am not exactly brand loyal but rather I pick lenses based on IQ and value. I highly recommend this lens ... until the next one comes along.

Comments about Sigma 8-16mm f/4.5-5.6 DC HSM Ultra-Wide Zoom Lens for Pentax Digital SLR:
8mm is addictive. Fun to use. Very sharp. Great colors. Need to learn how to use the perspective but it is amazing to say the least. First non Pentax lens I really like. The quality is quite stellar as well.
Cons: Cannot use filters.
I have used the Pentax DA 12-24mm as well but after I got this Sigma I let go of it. I take pictures outdoors so the constant f4 did not really matter to me as much.

This is best zoom ultra wide lens for crop sensor.
Easy focusing in AF and Manual modes. Looks great also. Performance better than any Pentax zoom lens.
Must have good flash to use it indoor.
