Re: D-FA HD 15-20mm f2.8
I’m a bargain hunter myself and really worked that angle before making the decision to go with the 15-30. I already have an FA 20-35 f4, so I was looking for something that would do better . The 20-35 is good at the wide end when stopped down to f8 or 11 and is very good at the long end. But at the 20mm end the combination of CA, distortion, vignetting and poor AF accuracy can really hurt image quality. I used it on and off for a year and decided that it fell short of what I wanted. Initially I considered just getting a good 14/15mm or 20mm prime and leaving it at that. Contenders were the Rokinon 14mm f2.8 and 20mm f 1.8, Pentax FA 20mm f28 and IRIX 15mm. Without going into details, I didn’t feel like these lenses offered enough of a boost over the FA 20-35, each alternative failing on its own terms. (Though the IRIX is a lens I would look at if the 15-30 did not pan out). You mention a Sigma 14mm f3.5. I own this lens, bought new many years ago. I liked the results on slide film back in the day but on DSLR’s it’s no good. Maybe my copy deteriorated (though it was seldom used ) but its bad on APS-C and terrible on full frame. I usually don’t speak that harshly about a lens but I don’t even want to try to sell this one, because whoever buys it will be unhappy. After looking at the alternatives, I settled on he DFA 15-30. It’s not perfect. You can’t use filters with it without buying into a very expensive system , the bulbous front element looks like an accident waiting to happen, and it’s really big and heavy. But it’s super sharp, has incredible close focus, virtually no CA or light falloff, and an excellent zoom range. I’m hanging onto the FA 20-35 for situations where I want to use filters or want a light wide angle. FWIW - when I got the K1 I was prepared to replace both the the FA 20-35 and also my Sigma EX APO 70-200 f2.8 (the original film version of this lens, from the late 1990's). The Sigma proved to be a great performer - exceptionally sharp, great flare control (really surprised me) and while it has moderate CA wide open its very easily corrected. It's not ideal - poor close focusing distance (3 meters) and slow cam driven AF - but for me its fine. Upgrading it is off my list. So I agree there are a lot of underappreciated lenses out there.

RE: D-FA HD 15-20mm f2.8
I borrowed Larry's 15-30 for a couple of shots while we were in California in November 2016 - I confirm Mark's comments on exposure between areas of different brightness and boy, that barrel distortion! That was on a K5ii, maybe not so bad on the K1. Interesting lens, however, and very sharp.

Re: D-FA HD 15-20mm f2.8
I'm really glad you posted about using this lens for shooting the milky way.

Re: D-FA HD 15-20mm f2.8
I got it intending ti use it for landscapes but the close focusing abilities open up some other opportunities as well. The focal range is also pretty good for use on APS C and if it behaves nicely with infrared it might get some use on my IR converted k01, being a bit wider than the DA 18-55 WR that is on it.

Anyone who has that lens and camera body should definitely spend some time outside at night with them taking advantage of the combination. The other lens I often use for night photography with the K-1 is the Rokinon 24/1.4, which is fortunately much less expensive than the 15-30.

Re: D-FA HD 15-20mm f2.8
I took it out for a couple hours this afternoon, a little more dedicated test than just randomly shooting though the results are more or less the same. I'm glad I got it - though I have to rethink the camera bag situation in light of its size.

The third shot - the lake - give me hope since it was into the sun, though the sun was just out of the frame and lightly obscured but the cloud in the upper left. But I did do about 10 minutes of post processing to competss the tonal range and make a few other adjustments. This is definitely a lens that will take a little time to understand and master, especially at the 15mm end. I plan to take it out tomorrow for a more extensive test drive.
