I've got a 20mm f2.8 with KA mount and 58mm threads that focuses the wrong way but is otherwise a decent lens stopped down. Haven't used it for architecture, so I don't know about distortion. This lens was sold under Soligar and Spiratone labels, and I got mine for well under $100. I don't know what company actually made it.

There aren't a lot of good choices in K-mount for 20mm lenses, especially if you don't want to pay for a new FA 20/2.8 (assuming you can find one in stock somewhere...). The K and M 20/4s are impossible to find, and very few off-brands came in 19,20,or 21. I'm hoping the Adorama order comes through, and the lens doesn't stink, because I'm beginning to despair of finding any of the good Pentax glass on the used market any more.
