New short zoom?

I was looking at the Pentax 16 - 50mm until I read another thread.

I am looking for a 2.8 zoom, I already have a Sigma 10-20mm, Sigma 70-200mm and a Pentax FA 50mm 1.4

I was looking at the following and wondered what experience people had with them:

Sigma 24-70mm F2.8 EX DG HSM Lens - Pentax Fit - 589.00
Sigma 18-50mm F2.8 EX DC Macro Lens - Pentax - 308.00
Sigma 17-50mm F2.8 EX DC OS HSM Lens - Pentax Fit - 649.00

The 18 -50mm would suit my needs but does seem very cheap, is there something wrong with it?

Not had any experience with it but the price seems about right to me, the other two you mention are HSM and that will hike the price up.

Whats wrong with the Pentax 16-50? (apart from the distortion a 16mm)

As Mr Spider says (sorry, still not used to your new name!) it's the HSM pushing the price up, plus the 17-50 is very new and is OS as well. I don't think there's anything 'wrong' with the 18-50, I was very tempted by one myself purely because of I thought the macro, even a limited macro, would be useful for my walkabout lens. I ended up going with a Tamron 17-50 after finding a great used deal on one, but I still wonder how the Sigma would have been.

I'm have the same problems ^^

Is there any reason for you not to include the Tamron 17-50?
Some forum members here have one and I've read good feedback from them.

Also the Sigma 17-50 is very new and not even in the stores yet and spend last night finding a review without success so no one know how that lens is

I need a lens quite soon so can't wait for the Sigma so I'm most likely going to get the DA*16-50 if it does feel alright in the shop if not I'll wait for the Sigma 17-50 and try out which one is the better lens.

I would have also thought that the Tamron 17-50 would have made the list ... it is a very sharp lens ... and I have had great success my mine ... I had picked it for the 2.8 constant aperture ... and it saved using a flash in many indoor type situations ...

When I had researched this lens, I checked photozone.de where they had tested the Canikon mount versions ... and had this to say "The Tamron AF 17-50mm f/2.8 XR Di II LD Aspherical [IF] is a very serious performer capable to deliver some of the best MTF50 figures to date in this lens class." for the Nikon mount for what it's worth ... for the Sigma 18-50/2.8 they concluded "The Sigma offers lots of bangs for your bucks but the comparable Tamron AF 17-50mm f/2.8 SP seems to be a better alternative."

Maybe you look at some of these reviews at photozone.de (and others) before you spend the money ...

I had really wanted to get the DA* but the price tag was too much for me, and I wanted to buy locally due to all the reported SDM issues and such.
