31/43/77 sure, what about 20mm?

Maybe the K 20mm f4 or M 20 F4.

The corners on the M20 aren't good enough on the K-1, unfortunately.

Will give the 12-24 a try at 18mm+.

The Sigma 20mm f1.4 would be excellent if only produced in K mount - a perfect lens for night skies. Grrrrrr.

What about the K or the Cosina f3.8 or other 20-24mm manual focus options?

I don't know, I haven't got those so I can't test them. Suspect the K will be better than the M but I'd want to know about edges and corners before going for one.
