Pentax 16-50MM F2.8 ED or Sigma 17-50mm f2.8

Anyone have any suggestions on which one is better?. Looking to sell my 18-135mm kit lens and get something better. Also should I sell my 15mm limited and put the money towards another lens like the 50-135mm f2.8.

Have you read the comparative review? It sums things up fairly well. I'd hang on to the prime, though!

Absolutely hang on to the prime - it'll save you having to buy another one later . . . . . . .

Don't sell the 15mm. The Sigma 17-50 2.8 is a very good zoom. Focuses fast and silent. Cheap enough as well. I'm very happy about it. Keep in mind though that you will have to edit the exif of your files if you want Lightroom to be able to apply lens profile corrections. I have written on my website a small article explaining how to proceed to such batch corrections on a Mac.

+1. Keep the DA15mm. A great prime. Neither the Pentax 16-50mm nor the Tamron 17-50mm will give you as good wide-angle IQ.

I am thinking the similar purchase.

Either Sigma 17-50 or Sigma 17-70. It is just the possible focusing issue that makes me still thinking if I should go get one.

No focusing issue whatsoever with the 17-50 on my K5. Even less so since the latest firmware update. It's really like I have a new camera...

I will definitely keep DA15.

I have both DA16-50 and Sigma 17-50 f2.8.

Both are equivalent in size. I have 'shutter freeze' on one or two occasions with DA16-50 when my K5 is in focus (?early stage of sdm problem) but never with any other lenses. DA16-50 has 'the' Pentax colour/look, good contrast but soft at the edges. It may become obvious when the edge of the photo is essential in your work.
Sigma 17-50 is sharp wide open. Its output is warm in colour.

IMHO DA16-50 may be worth US$600-700 brand new but definitely not the current RRP. I pay US750 for my copy during the Black Friday deal from bhphoto. The Sigma 17-50 is great value for what it can achieve especially if you don't need WR.

If you really need the weather resistance, then go for the DA*16-50 F2.8 otherwise get the Sigma 17-50 F2.8

Can't compare the two, but I have the Pentax 16-50/2.8, which is a wonderful lens. Bought it in Japan when it first came out, and it's probably the one that's seen the second-most action in my kit - in large part as the SO picks it up and uses it as "point and shoot" lens on our *istD (in addition to on the K ...)

I'd not let go of the prime, though, but hold on to it and save up for either of the zooms later....

Given the experience I have with the Pentax 16-50/2.8, if I was to acquire a lens in that range again, then I'd not hesitate getting the very same as I'm quite happy with mine. That said, I am given to understand that the Sigma 17-50 is very well appreciated also, at least around here, so....

I guess that it in an ideal world you'd bring your body into your favorite photo-pusher's shop and try them both out: take some pictures and compare later / at home, see how they feel in your hands etc. - or, find some pentaxians and organize a meet-up and play with theirs?

Just got the older Sigma 17-50 w/ OS here on the forums used and very happy with it so far. Lightroom 4 will let me do a profile fix with it, though it does take another mouse click than the usual. Haven't really tested the bokeh but it seems sharp, focuses fast enough for my uses and is silent....I had the Tamron 17-50 before on a Canon 20D and it was super loud.
