The DA15 won't work- too slow and I need higher shutter speeds for fast moving musicians. This is why I'm looking at the 2.8. I wish the FA24 and 28 were wider and/or cheaper, but it's not to be, unfortunately. I'm thinking of the 21, but slightly too slow, too narrow to consider.

Don't forget that the wider the angle, the less motion blur you'll see for a given shutter speed.
As I mentioned earlier, 1/30 sec is usable at f/4 and ISO 3200 (on the K5 even more so that the K-x).
If your musicians are moving so fast that that would still blur,
I would start to see the blur as a pictorial value, rather than something to be supressed.
Or turn off the SR, and pan.

I'm once again trying to decide between these two lenses and was hoping this time around that I could get more feedback, particularly about what pros the Tamron has going for it. Cheap, it is not, but I'd only want to buy a FL like this once.

IMHO, I believe the Samyang 14mm 2.8 trumps both of these lenses hands down.

Cool. I want AF, though.

The next part of the question asks of you're able to qualify your post with personal experience.

Absolutely - had one for many months (sold it here on the forums) and the short focus throw allows for really quick MF'ing while using CIF...

I mean have you had the others?

And I guess the part where I said I want AF makes no difference.

I'd suggest the FA 20/2.8 prime lens. I tested it against the 15/4 DA, and it's so much sharper especially in the corners, I could hardly believe it. I even equals the 12-24 at all f stops, and is quite sharp at 2.8. It's the best wide Pentax prime right now, IMO.

The Photozone tests at f/8 on the K10 suggest otherwise.

I have the DA 15 and the A 20/2.8 (optically the same as the FA 20/2.8),
and I haven't noticed that much of a difference.
You do need to be aware of the field curvature on the DA 15, however.

I disagree. All the tests of the 15/4 DA, incl dpreview, say the SAME thing....the DA 15 has poor edges at f4 and f5.6, and not perfect ever. What good is a 15/8.0 lens??? My copies of the 20/2.8 FA are tack sharp across the frame from F4 on, and very very good at 2.8. And the flare resistance of the FA 20 is superb, like the 15 DA. And all the reviews also say what I found...the Pentax 12-24 is a superb lens, and is much sharper across the frame than the 15/4 ltd.

No, in this case as well, the Photozone tests at f/8 on the K10 suggest otherwise.

At similar apertures, the 15 Limited is sharper than the DA 14, and way smaller. Since most people use this wide of a lens for landscapes the fast aperture is less important.

For your stated purpose of using that wide max aperture, neither the DA 14 nor the Tamron 14 is particularly sharp wide open.

You'll get much better results from something like the Tamron 17-50/2.8, Sigma 17-50/2.8 or DA* 16-50/2.8. Unless you're right up in the band's faces 14-15mm is probably going to be too wide anyway.

Really the ideal setup for what you desire is an FF body and a 24/1.4. Or for not quite as ridiculous money the Nikon 28/1.8.

Correct, in reality, though others do make good wideangle lenses for crops. Pentax, for some reason, does not. The 15 might be ok, but it's still an F4.

Pentax doesn't even have a good, fast 24 to allow the K-5 to compete with an X100.
