I recently purchased a Pentax K-5. Rather than duplicating with an equivalent of the 10.5mm I use with my Nikon D300, I am considering the Sigma 8-16mm for my Pentax system. Does anyone have experience with this lens and care to share their thoughts? If there are other K-5 users in this forum, what lenses are you getting the best results with?
Thanks for the responses. I've already been reading up on the Sigma 8-16 for standard ultra-wide-angle work. In the film days one of my favorite lenses was a Voightlander 12mm (rectilinear) which I used with my Contax G-2. That was my main walk-around lens for a couple of years. (Yes, I have UWA addiction. ) My real question is whether anyone here has used the Sigma for 360 panos and what they think of the output quality for that purpose. I'd like to avoid buying yet another lens I don't have to. If it doesn't make the cut, I'm leaning toward the Samyang 8mm. From what I've read about the Pentax 10-17, it's slightly softer than the Samyang.
As I already mentioned, the Sigma 8-16mm is not one of the favorite lenses, which means it is not used very often. Some of us use Sigma 10-20, or Tokina 10-17. Sigma 8 is one of the favorites like Nikkor 10.5, Nikkor 16, Canon 15, Samyang 8.
I am quite sure that if there was someone on this forum using this lens you would have got an answer. May be you ask on panoguide as well.
Having UWA addiction, the Nikkor 14-24 would be the right lens for you. Have a look at the panos of Vincen, all taken with 14-24. Well one of the big boys, but you get a lot for the weight. One of the best lenses on the market in this segment.

I've tested the Samyang 14mm f/2.8 but no images on my blog yet.
I'm also testing the Pentax DA* 16-50mm f/2.8....
Did you try the Pentax DA 10-17mm? It's the Tokina and it's pretty small. I bought a Pentax kx and the 10-17mm but I just didn't like the camera and sold it. Lens was ok. Still got the lens and I'll make you a good price if you're interested. Contact me off list
