My question to you, is how do you plan to use the lens? If the situations are primary static - where the contents of the scene are not moving, then any of these lenses are very good, with a tripod and external shutter release.

I have the 10-17, 12-24 and 16-45 and they are excellent, especially the 12-24. The 12-24 is very sharp at f8, good at f4 - wide open. To get to f2.8, you need to use the *16-50, however you will probably need to stop down a bit to get into its sweet spot.

Sigma 10-20mm f/3.5

Does anyone have the:

Sigma 10-20mm f/3.5 EX DC HSM ELD SLD

What do you think?

Any quality-control issues?

It looks awesome on paper, but I haven't tested it in person. I'm looking to maybe get this one.... unless there is a better choice....?

I use a 6.5mm Opteka Fisheye, 10-24mm Tamron and 15mm F2.8 Sigma with my K-7.

Or the DA 14 F2.8 is a possibilty if one needs a fast UW lens.
