My dream lens from Pentax would be a wide angle prime that is fast and well corrected for Astrophotography usage where astigmatism, spherical aberration, curved focal planes and coma are killers. Something like the Sony 35 f1.4 GM, the 24 f1.4 GM, or the Sigma 40mm f1.4 Art.
Reading this thread though, I see I am probably alone on that front, so I don't think it will be coming any time soon haha.
I love all the dedicated astro features Pentax adds to their cameras (I regularly use astrotracer and the night view mode), but its a shame not to have any lenses that can make best use of them.

Originally posted by MossyRocks If it is good as the other new DFA * primes I would be all over that for astro. Running at about f/2 and 35mm with great results would be a dream instead of starting at f/2.4 for not awful results with the DA 35/2.4.
Do you own the Sigma 35mm f1.4? I find it usable wide open for astro, especially in a pano where I can crop out the extreme corners. For excellent performance across the whole image circle, I cannot fault my copy from f2.2.
I read all your lens reviews that feature sample star field image. They are very helpful! I can send you the same star fields shot back-to back from f1.4 to f2.8 for this lens if you are interested.
