Tamron 17-50 f2.8 is great for the price.

Is the Tammy 17-50 f2.8 a lot better than the DA 18-55? 'Cuz I might just save up my pennies for one... Won't be right away, but down the road it's a possibility.

At the wide end, the Tamron 17-50 at f/2.8 is already sharper in the far corners than the 18-55 gets at any aperture. It's also sharper in the center but the difference isn't as pronounced. As you zoom in, the difference isn't as much but the 17-50 stays ahead pretty much the whole way. It's also got the faster aperture, of course.

One big asterisk though: my copy of the 17-50 needed a -5 AF fine adjustment on my K-r. This is apparently pretty common with this lens. When I had a K-x where you have to go into debug mode to do any AF fine adjustment, I got consistently soft results because of focus inaccuracy.

Yes. I use it instead of primes for tripod-mounted landscape images at focal lengths below 50mm.

That could be a dealbreaker. :-(

The Tamron 17-50 usually goes for $350 used. The DA 16-45, Sigma 17-70/2.8-4.5 and 18-50/2.8 can be had for under $300. There was a "macro" version of the 18-50 that's a little sharper than the original
i would go with the tamron if you got the $$ but the sigma lenses are good lenses i know from experience

Your best true $200 option is probably Sigma's 18-50mm f/2.8-4.5. It has a few features going for it - quiet HSM focus, internal zoom and a bit faster for low light - but I had one and it didn't wow me. When you consider that many 28mm primes get very good results (often shown off in this forum, sometimes by me!), it's hard not to put some of that $200 into older 28/35/50mm lenses, and keep the 18-55 for times when zooming counts or sub-24mm is needed.

The Tamron 17-50mm F2.8
I'll throw my vote in too for this lens. Definitely sharp!

The OP said a couple hundred bucks or less...where can you get the tammy 17-50 f2.8 for that price?
If you are shooting low light, handheld, then you might have to spend more...but I took this with the kit lens:

All sizes | IMGP9703_DxO_tonemapped | Flickr - Photo Sharing!

That was taken with the 18-55 WR. I find it pretty sharp.

There are a ton of truly great photos that have been taken with the kit and there is even a lens club on this site devoted to the lens.

https://www.pentaxforums.com/forums/lens-clubs/45425-kit-lens-club.html

That being said, it is not so good at the wide end. Unfortunately, there are few, if any zooms that offer a significant improvement in performance below $300, even used. One can do a little better with primes at 20mm and wider, though things are still pretty pricey. So, what to do?

As someone who tends to shoot wide, I will admit to using the kit and my Zenitar fisheye for all my wide angle digital work and have done so for about 5 years. I am too cheap to buy the DA* 16-50/2.8 or even the DA 15/4.0 Limited. When I want to do serious wide-angle work, I pull out the film gear and shoot at 28mm on 35mm or 90mm on 4x5.

Maybe the older Sigma 17-70 2.8-4.5 would be ~$200 second hand? It's a good lens, better than the kit.

I use CDAF in live view on the K-x
for critical focusing with the Tammy
(i.e., when it's open wide at longer focal lengths).

From personal experience, Sigma 17-70 2.8-4.5, I upgraded to this lens from the kit lens.
Very good lens.

This one? Sigma 17-70mm F2.8-4.5 DC Macro Lens Reviews - Sigma Lenses - Pentax Lens Review Database

Looks like a good one, from the reviews. It reaches a tad farther than the 18-55, plus it has macro abilities, which would come in handy. I think we have a winner! :-) I'll keep an eye peeled for one.
