Had those off - thanks for the reminder that resolved my confusion.

Most of us lose track of which lens is called what in your harem. Which is that?

And in APSC the existing lineup already gives the nod to zooms going wider than primes. DA 15 is the widest prime, but the 10-17 and 12-24 both exist with wider FOV. I think you guys have it right, a 20 or 24 would be priority 1 since the 31 exists and is close to 28 already (albeit expensive). The 15-30 is there for really wide angle enthusiasts.

The link I posted earlier was to Sigma and they had a refurbished (or perhaps several) for $399.

Too many flying topics. I realize you meant that - my point was you don't have to match 10mm on full frame and the 12-24 Sigma posted earlier is full frame and has a FOV wider than that - but it was mixed into the discussion with the 12-24 Pentax which confused things I think. Sorry about that.

My impression was that the FOV in question was on APSC - and there is a Sigma 12-24 that is Full Frame. I posted a link earlier. But I get your point about APSC lenses.

Is the 12-24 Pentax not ultrawide? That's an 18mm FF equivalent. Not to mention the 10-17 Pentax... but that's a fisheye.

That's why he said FOV.
And it is entirely correct to put any sensor as the frame of reference for discussion. Are you saying an 18mm lens on APSC isn't an 18mm lens? Of course not. Nor is he saying that a 28mm lens on FF isn't a 28mm.
The point which is being lost in people stirring up the mud is that he feels like wide angle - on Pentax - is easier to accomplish with APSC lenses like the 10-20mm from a cost vs. quality perspective.
I'm not the expert owning a K-3 and not having a K-1, but I think this is a valid question to pose and get feedback on. I do know that I have read that some of the ultrawide angles for APSC cover full frame over part of their range. But I'm not sure what level of IQ these have at those ranges or the exact ranges covered.

Not a 10-20 but actually wider on FF than the 10-20 on APSC:
