Sigma 17-35mm f/2.8-4 EX ASP HSM (ver. 1) - opinions?

Someone is selling a Sigma 17-35mm f/2.8-4 EX ASP HSM (ver. 1) and I have seen images from it but most are from Canon/Nikon bodies, all look fine to me. I'm just inquiring if anyone here has experience with this lens to get some real-time feedback. TIA!

I have this lens and its quite allright.

Colors are good. Sharp enough, maybe only extreme corners are a bit soft wide open at shorter end of the zoom. Let me get some images...

I have also enjoyed the Sigma 17-35 DG EX, which I am assuming is the lens referred to in the OP. The nicest thing about it is that it covers a full film frame. The corners are not tack sharp, but there is no way to get a decent 17mm on film for this price.

The extra speed of the Sigma, and the 17mm even on APS-c come in handy for tight, dark spaces.

Great examples from both of you, thanks!

There are 2 versions of this lens, which one do you have?
These photos show the visual difference;

I think there is some confusion about this lens in Pentax mount. I have the Sigma 17-35mm f/2.8-4 EX DG lens, it is not HSM, and there is no window on the barrel of the lens. Sigma did not make an HSM version of this lens for Pentax (and perhaps because of that difference it also doesn't have the window). There was an optical redesign between the DG and non-DG versions, and the earlier (non-DG) version takes 82mm filters whereas the later (DG) takes 77mm. For more on the changes, see this review:

Sigma 17-35mm f/2.8-4 EX DG

So far in my limited shooting with it, I've enjoyed it (I don't have enough experience with it yet to review it though). I wanted a lens that was better quality than the kit zoom, could go wide, would be backward compatible with my film bodies, could do f/2.8, and take filters. This was one of the few that fit the bill.

I have to confirm what nater posted. There was no HSM version for Pentax and AFAIK neither version had the window on the barrel.

I own the 2nd DG version ( the one that takes 77mm filters ). Visually its closer to the 2nd pic you posted.

Thanks for the clarification on the lenses. Still wondering if its a better solution over the kit... I'll go in person, take a few shots and come home with the results in the next couple of days.

That's the one I have as well. No window, takes a 77mm filter and no HSM. It is neither of the two pictured above.

The one I got was an improvement over the kit, though it is much bigger. The extra stop of speed is welcome for focus and the IQ is a bit better. It is not as much of an improvement in IQ as the DA17-70, though. Mine was really cheap, and the superwide full frame capability is a real bonus.

I got the chance yesterday to shoot this lens at 20mm on film along with the Pentax M20/4. The 17-35 acquitted itself nicely.

Sigma:


Here are 100% crops from the Sigma and the Pentax M20/4 both stopped to F8. Allowing for my failing to match the magnification in the two shots, the resolution of the Sigma is basically indistinguishable from the Pentax prime, and at ~F2.8, it is easier to focus.
However, you could put about 4 of the little Pentax M lenses into the bulky Sigma.

I'll let you see and try the lens first if you like it.
