Looking to replace my 18-55 with somthing much better.

Hi guys with my DA*300 in the shop getting repaired I took the 18-55 out of the bag for a few family shots. Getting home I was shocked at the poor IQ what is a good replacement for this. I would like something for landscape and family type photos.

Probably the Tamron or Sigma 17-50/18-50 equivalents. I have the Tamron, and while it's not the same level of build quality as something like my Sigma 10-20, it's a very sharp lens.

+1 for the Tamron.

I use the Tamron 17-50/2.8 in place of my primes for landscapes [except at 50mm]. It is also my most used lens for product shots.

The kit 18-55 should be considered an f/8 and be there lens, or you'll indeed be disappointed. You'll find more joy with the Tamron or Sigma 17-50 or even the Pentax DA*16-50, as then you wouldn't have to limit yourself to f/8 to get good image quality.

Pentax's own 16-45 is a decent lower price replacement. Pretty sharp, and offers a nice wide angle.

Edit: Also, look for used stuff if possible - Could probably get a great lens for 200-300.

Did someone mention the 3 different 17-70's ? Pentax's own DA17-70 and the Sigma 17-70mm/f2.8-4.5 non HSM as well as the newer f2.8-f4.9 HSM version (talk of the street has it the older has the edge over the HSM version)

I've gone through my fair share of standard zooms and I've found that the two best were:
Tamron's 17-50 for sharpness and flare
The DA* 16-50 for build, handling, "pixie dust"
In the end, i stuck with the Tamron for is superior technical IQ in studio.

Any of the 17/28-50/70 f/2.8-4 options from Pentax, Sigma or Tamron will give you great results

The kit lens' Achilles heel is the uneven quality; mine is good enough that after spending time and cash on several other options* I stuck with it. I did not try the Tamron 17-50 though, and it's obviously well spoken of here and elsewhere. May it serve you well!

* "other options" = Sigmas 18-200DC, 17-70 + 18-50s f/2.8-4.5, DA18-135

I just bought myself the Tamron 17-50mm f2.8...about 10 minutes ago.

I based a lot of my decision making on this thread, and reading a BUNCH of reviews including those on the pentax lens page in this forum.

Hope it all pans out for a much better lens.

That kit lens truly does suck.

One question I would have about the lens I bought...right now my camera bag is pretty hefty and I am looking to lighten up some....

I have a 28mm Pentax-A prime...I am thinking that the Tamron can replace this one for when I travel and walk around and so forth... I will probably keep the 28mm prime but maybe not have it in my bag at all times...I might lighten up on a few 50's and say carry with me either my f1.4 prime or my Pentax-A f1.7 (I also have a f1.7 prime that is manual that I can leave at the house too so I can travel lighter...)

I am wondering with a good quality zoom if it would be wise to leave the 28mm at home from time to time....what would be the strengths and the weaknesses there other than you have more aperture ranges with the prime?

It must be the "luck of the draw" with this lens, because I favor my wr18-55 over my (older Sigma) 17-70. There's also zillions of photos on PPG, Pbase and Flickr taken with it that are proof that good pics can be wrung out of it! Obviously, if it were faster it would be better, but mine has excellent colour and contrast and the only thing I would like to improve it would be to add an extra aperture blade.

No one mentioned the 18-135, and while it isn't quite as good as the 17-50s mentioned, I do find it to be a solid performer if you apply lens correction afterwards. Additionally, maintaining whether sealing and a useful zoom range are nice features.

Edit: I should have asked if this is going on a weather sealed body, otherwise, my main point is moot.
