Any opinions on this one?
Sigma 10-20/4-5,6 EX DC.

I have given up on the Pentax 10-17 fish eye that i wrote about in another thread, butr i still wan´t a super wide lens, but not necessarily fish eye.

I have this lens. Seems quite good but I'll admit I haven't pixel-peeped images with it, either.

You might want to consider the Tamron 10-24 f3.5-4.5. It's a little faster, has a little bigger range, and delivers consistently good results. I believe that it may be a little less expensive also but not sure on that. I get very nice results with my K5II.

Hope that's useful.

Excellent build quality, and good image quality IMO. Used for landscape and on a tripod I have gotten some great pictures. Hard to compose well with an UWA, but that is a different issue. Thought I would use it a lot more than I ended up doing, and ended up selling it and getting a 15mm limited. It was big and bulky, so I always seemed to end up leaving it back. Never an IQ problem, though.

I've had this lens since 2008 and love it, although sometimes I'd like a little more reach. It certainly seems sharp enough to me - and I've printed some 16x20" images from it with no problems at all.

One thing I like to do is exploits hyperfocal distance - makes for some dramatic shots.

You need to watch any filters you attach - at the 10mm end they need to have very thin mounts to avoid vignetting.

There are plenty of opinions about it in the lens review database, and you can see what it can do on Flickr (Flickr: The Sigma 10-20mm Pool) and other sites

Good luck with your research

The winning contender is : Sigma 8-16mm F4.5-5.6 DC HSM
In term of widness and sharpness !

The Sigma fared very well in the shootout here on PF:

Just so you know, though, the 10-17 de-fishes really nicely in Photoshop:

Original

De-fished

Also, at 17, it's not very fishy. It is a little, but not bad. At 17, it's about the same as a 12mm wide angle, so still VERY wide.

And the same shot just using lens correction in LR (note that this does NOT work well at 10, really need PS at that angle).

At 13, it's moderately fishy. But remember how wide this really is, and about half of what you see is perspective distortion.

The 10-20 is quite good, I think. The reason I don't use mine much is the size and weight. The DA15 is so much lighter and is therefore always in the bag.

As others have said, you should consider the Sigma 8-16 and Tamron 10-24 as well.

Ok guys thank you for NOT making my descision any easier!

Right now it looks like it will be the Tamron AF 10-24/3.5-4.5 Di II. I have the Tamron 17-50 and is quite happy with that one.

.......or a Pentax 15mm f4 limited.

I Went along and bought the Sigma 10-20/4-5,6 EX DC and i like it a lot! The image quality is great and the range 10-20 is really fun.
I hope my example Picture is shown below.
