Thanks for the postings. Can you send me the original "hi-rez" jpgs from the camera. I PM'd you with my personal email address.

Also, how did the focusing speed compare in lower light compared to the kit?

This was exactly the type of post I was looking for.

Reading the review at photozone.de shows the kit lens to be pretty good at 35-55, even opened up. And, you photos show this.

I'm also looking at getting the lens, but my needs are more for the lower light/indoor photography.

Would it be possible if you could take a few pictures at 18mm at 2.8 (Sigma only) and then 3.5 (Pentax & Sigma) I suspect this is where a difference will be seen.

Any comments on the handling?

Not much of a Hijack ;) I would be interested in the opinions from someone who has both DA* 16-50 and the Sigma 18-50 Macro EX. Weather sealing and quieter motors are a nice feature of the DA*, but they are less of a requirement for me.

I agree it would be ideal! I certainly agree the new lenses are fine and offers other great features like ultrasonic motors, weather sealing, quick shift and better optics.

But, with the more than twice the price, it's out of my price range.

The Pentax 16-45 F4 is also in the price range (with rebates) that I've considered -- but still looking at Sigma 18-50 F2.8 Macro for the faster lens.

Happy K10D owner here.

I'm currently looking to get a lens to replace my 18-55 kit lens as my new general purpose walk around lens.

I find that I tend to shoot more on the wide side and often times under less than ideal light.

I first considered the sigma 17-70, but then started reading up on the 18-50ex macro (the newer one)

For me, a faster lens is more important than a few extra mm.

I've read a few reviews 18-50 ex macro (though most are based on the non-macro version), but certainly the 17-70 is discussed much more. Both are in the same price range.

If anyone has experience with the 18-50 ex macro, I'd be happy to hear your opinions.

How is it wide open?
Hows the focus speed as compared to the standard kit lens?
Build Quality?

The new Pentax sdm lenses look nice, but they're a little on the pricier side for me.

Thanks

Stephen
