The gallery picture is only a minor crop to straighten, rather than crop to APSC. The 12-24 is not ff compatible but it's not bad to use. Sharpness to edges is surprisingly ok. Centre sharpness is plenty good enough. So knowing the limitations then it's perfectly usable on ff. It's main issue for me is chromatic aberration, but that is no worse than on crop sensor. From 17-24mm it doesn't vignette.
I don't use it that much - the 31mm is my go to landscape lens. I would have gone for a 15-30 but for the required investment in a whole new filter system. I was hoping that Pentax would make the wide prime (20mm?) on the roadmap - but that has been kicked back again so probably won't ever arrive. Also annoying that Sigma won't make their lenses in K mount. So my preferred option is the Irix 15mm (if you can find one) to use alongside the 31mm.
The following examples are all taken with the K1 and 12-24 with only a small amount of cropping from the long edge, or none. I am to blame for the dark edges, not the lens. Furthermore, as none of them are ever likely to be printed at all let alone printed large then quality perfection doesn't matter. Although I reckon they would stand up to all but the pickiest critic (which is me anyway). The only pictures I'm likely to print with this combo are the pierscapes, where edges and corners are featureless so the 12-24 works just fine for those:

What mock-up primes were those?
I can't think why anyone with a 43 or 77 would go for a 50 or 85. There are older lenses at those focal lengths that work very nicely on ff too.
I think there are rather more of us that don't wish to go for the 15-30 (terrific lens though it well may be) because of the size and because it requires a whole new filter system. Wide primes are an obvious hole in the line-up and should be prioritised.
Ricoh are not doing very well. The vast majority of the company that is, of which the camera business is a titchy (and by all accounts unprofitable part). I hope that doesn't impact on everything except the Theta, but it well might.

I absolutely need a DFA 20mm f1.4
I would also like a wider prime.
Sigma make a 20mm f1.4 which isn't in K mount.
Irix and Laowa deliver wider in K mount - if you can find one in stock.
I have an M20mm f4 - it just isn't up to the K1.
The 12-24 isn't up to the K1 either (it's not supposed to be).
Other roap map lenses like the standard and medium telephoto primes are not a priority in my view (or even necessary) since the Ltds, inter alia, are excellent on the K1.

Hints, tips, advice on how to get the best out of the camera and it's files too, not just RTFM!
1. Put an expensive lens on it,
2. Stand in front of something interesting before most people have woken up.
3. Put it on M and try a few settings until it comes out right.
