I found this on Amazon.... get a new Sigma 8-16mm for $530. Has the new price been dropping lately?

Personally, I would get the DA10-17 if you already have the 12-24 and like it. It is wider @ 10mm than the 8-16 @ 8mm, even after de-fishing in Lightroom's lens profile, and *much* wider uncorrected. The fisheye perspective gives you different creative options given that you already have an extremely wide rectilinear lens.

I had the 8-16 for a month, and really liked it. Images from that month can be seen HERE. I just love my DA10-17 and DA15 more, and couldn't justify keeping another big lens.
Thanks for the link to the Flickr shots. Some of them seem very sharp. Did you apply sharpening in post-processing?

Yes. Doesn't everyone?

I have had all three, I purchased my 12-24 back on film, it's a cracker of a lens, I bought the 10-20, and found the barrel distortion just too much, I sold it in the end. I bought the 8-16, yes, it's wide, but, again, lots of distortion. I still have it, but use the 12-24 far more.

The 17-28 is excellent, as is the 10-17.

I'm still trying to decide whether to keep my Pentax 12-24, or replace it with either a Sigma 8-16, a Sigma 10-20 f3.5, or a Sigma 10-20 f4-5.6.

In any case, I had been checking out used versions of the 8-16mm and then was shocked to see the price new. Why would it have no warranty?
I haven't read through all the posts to see if anyone has given you advice, but here's my take on your choices:
1) The super wide-angle of the 8-16 is wonderful. It takes in almost as much left-right as my fish-eye. The IQ is more than one could hope. Major drawback is distortion at the edges, especially if the lens is not perfectly level, but that's true of any ultra-wide.
2) The 10-20 is much smaller, lighter, cheaper. Published tests suggest that the older variable-aperture version has better IQ, and it can be had for bargain prices (under $300).
3) 2mm difference in FL may not seem like much, but in WA it makes a significant difference. I could easily see the WA difference when I shifted from a 17-70 to the new 16-85.

If $ is tight, look for the older version of the 10~20. If you have the $, go for the 8-16. You'll be happier with either than with the 12-24.

If you already have the Pentax 12-24 I don't think it's worth it. The Sigma 8-16mm is difficult and expensive to mount filters and is quite a heavy lens. I also believe there is too much overlap with the Pentax given it is a relatively expensive lens to add to your kit bag.

The fisheye gives you a quite different field and point of view and is super lightweight. I also believe it is different enough as well as being relatively inexpensive, especially in the USA.

Yup. Deep down I'm thinking the same thing. I just ordered a Pentax 10-17.
