ultra wide angle for full frame Pentax

Heebie

I have a k-1, and f 2.8 from 28mm to 200mm.
I'm looking to get something to cover below 28mm. Maybe 15-30 or prime at 24 or 20.... But I haven't seen much available in that range for full frame. Mostly aps-c specific.

I'm not bothered by used etc... If anyone knows even since models I could look for, I'd appreciate it.

Good choice for your full frame K1 (and I'm not jealous, you having a K1, no not at all)

I found an older version of this that doesn't support autofocus, but does support auto exposure. According to specs, the optics are identical.. but it was a lot less expensive than trying to get the new one. (hundreds less.) I can deal with manual focusing, especially since I'm likely to be in a near-infinity focus situation with something as wide as 20mm in full-frame.
Now if I can only find a nice fisheye cheap!
