I am very happy with my DA 12-24. It is a very good lens. Check out my Flickr site for a set of samples.

Does that mean you want only Pentax lenses? Or just that that's all you have so far?

I have the older/slower 10-20mm sigma, and am pretty happy with it after finally getting a decent copy. By all accounts the 8-16mm sigma is sharper, but if you want one of those it appears they're getting hard to find in Pentax mounts. I'm sure 8mm would be preferable to 10mm, but I'm also sure that 10mm is preferable to 12mm. I probably wouldn't sacrifice 2mm for better optical performance, because for me the sigma is "good enough" for now. I only use it at smaller apertures, because almost inevitably you have very close and very distant objects in the frame, and while you get a lot of depth of field with wide lenses, you tend to need it, too.

You do not need extreme wide angle for landscape. Unless you want those mountains in the background to be really tiny instead of as impressive as they are.

Depends on subject. DA 15 is great if the subject is not at infinity. If infinity, then a telephoto zoom or telephoto prime emphasizes the size of the distant subject. I have no mountains locally, so the DA15 is my favorite landscape lens.

+ 1 on the 12-24. Lots of flexibility. Wider than the 15, longer than the 21 :-)

I would first start with the lenses that you currently have and stitch. You can use Microsoft ICE for free.

For single shot landscapes, DA-15 ltd and Sigma 10-20 are both very useful and produce good IQ for the UWA range. DA-15 is also very flare resistant for shooting into the sun.

But as @interested_observer has pointed out, stitching might be a very good way to start with wide landscapes assuming they have nothing moving in them. You also can get much higher resolution this way than the default of your camera if you wish to print larger posters.

Can also recommend Hugin for stitching. DA-35 f2.4 is a fine lens and FL for stitching landscapes, but focal length above this is viable.
