Anyone try this on a K1 yet? I'm considering getting myself a late Christmas present. How badly does it vignette? If it's not too bad, I could probably "fix" it in Camera Raw. An alternative might be the Pentax HD PENTAX-D FA 15-30mm f/2.8 ED SDM WR, which would have roughly the same field of view on the K1 as my Sigma 10-20mm F4-5.6 EX DC has on the K3. The Sigma vignettes like shooting through a port-hole from across the room on the K1. The only problem is the 15-30mm f/2.8 costs 3 times as much as the 15 f/4.
That, and the 15-30 is huge lump of solid glass. However, for me, that lens nearly represents the point of getting a K-1. The ability to have a fast, wide weather sealed system. Optically, I'm quite happy with the 15-30, although things do get a bit weird around the edges of the frame at the wide end.
Another lens that works well on the K-1 particularly for landscape work, albeit manual focus, is the Samyang 24/1.4. I've seen several articles claiming it to be one of the best, if not the best, astro-landscape lenses available.
I agree with Mark on the need for weather sealed primes for the K-1. I'd think that it would be fairly simple to take the optical design of existing lenses and just make weather sealed versions.
Ricoh could do wonders for their lens lineup if they just made a deal with Samyang to produce weather sealed auto-focus versions of some of the Samyang primes (85/1.4, 24/1.4 ...)
