Pentax brand solutions

There's the DA 14mm f/2.8. The DA 12-24mm f/4 , though on stop slower, reputedly has just as good IQ and gives you more flexibility. If it's wide enough the DA* 16-50 is f/2.8, but I prefer the lighter and much cheaper DA 16-45 since the IQ is just as good.

When you get really wide I don't see much need for faster than f/4, except that it helps the viewfinder image.

Forthcoming is a DA 15mm Limited that I anticipate greatly.

I wish Da 15mm is coming out as planned.

There are not many fast wide primes besides Da 14mm f2.8

If you want really fast and fairly wide, grab a Canon 5D and the 24mm f/1.4L

Otherwise, 14mm f/2.8 would be good. Hopefully Pentax will release the "Tokina" 11-16mm f/2.8 in a Pentax-ized version.

Sigma make a 30mm f1.4 - which is wider than a 50mm (although undeniably not a wide angle lens). They also do a 24mm f1.8 and a 20mm f1.8, which google says both come in Pentax mounts.

Sigma 24mm f1.8 is a good performer with so so bokeh. Good money for the optical quality

Sigma 20mm f1.8 is not so good on DSLR. Sharp centre weak corners with bokeh at best being netrual. Bulky though.
