Best wide angle lens for the pentax k x?

For the Pentax K-x, my pick is the Pentax HD DA* 11-18mm f/2.8 ED DC AW. It covers the wide end at 16-27mm full-frame equivalent and stays bright at f/2.8, which matters indoors.

If you want to go wider, the Tamron SP AF 10-24mm f/3.5-4.5 Di II LD Aspherical (IF) gives you 15-36mm full-frame equivalent in one zoom.

For a lighter setup, the [Pentax smc DA 14mm f/2.8 ED [IF]](/gear/lenses/pentax-smc-da-14mm-f-2-8-ed-if/) is a small prime that frames like 21mm on full frame.

If you want something more specialist, the Laowa 12mm f/2.8 Zero-D is the widest prime on the K-x list, with a view like 18mm on full frame.
