kit lens vs Sigma 17-35mm f/2.8-4 EX DG IF Aspherical

Hello everyone,

Noticed that Amazon is selling the Sigma for pretty cheap and was wondering which you think is better...

I'm attracted to the fact that this lens appears to be faster which will be helpful for my indoor candid pics w/ out flash. I've only found a couple reviews of this lens and they seem to be pretty positive, but most of the reviews are for canon/ nikon gear.

And perhaps those who are buying a k10d (sans rebate) now may be interested what other options are available besides the kit lens in the k10d kit which seems to be selling for around $110 more than just the body alone. In this case, the Sigma lens would be around $50 more than the kit lens if purchased w/ the k10 body...

I don't know if you've checked out the sample images of the 17-35 on Just in case you haven't, then here's the link:

If you want to compare them with the kit lens, here's the link to the kit lens samples:

I looked at getting this lens myself, but the IQ on the different shots seemed to be inconsistent (of course you have to consider photographer skill, as well). I've got the kit lens and will have the Sigma 17-70/2.8-4 by the end of the week. Here are some sample photos from this lens:

If you've got the extra money, I would say get the 17-70, as you can get them gently used for around $300.

For the money, the kit lens isn't bad at all and covers a wider range than the 17-35. If you decide to get the kit lens, it would actually be cheaper to get it separately rather than buy it with the body. If you go on the Marketplace or Fleabay, you'll find that you can pick up a gently used kit lens for around $50 or so, which is a lot cheaper than $110. What happens is a lot of people will buy the body/kit lens combo initially, but eventually upgrade to a better lens in this range. I haven't decided yet whether I'm going to hang on to my kit lens or get rid of it once I get my 17-70, though.
