Good all-round lens

Summary: A really good all-round lens. I've got a high-quality 18-50mm lens from another maker, and my plan was to swap between these two - as my 18-50mm has a better low-light performance etc. However, I've been so happy with the overall performance of this lens so that I have hardly put my old lens on the camera ever since. It's relatively light, and build quality seems good. I've been happily using the lens for over a year with no mechanical or other issues.
Excerpt: I was hesitant to buy this lens because of all the negative review, but the samples here really impressed me. I've found that yeah, the corners tend to be on the soft side, but this rarely bothers me because I'm never putting my subject in the corner. The softness is most noticeable at full telephoto, but at that point your subject is usually near the center, and everything else is out of focus anyways.
Summary: I never realized how important WR really is until I spent time at Niagara Falls. I did not dare to take my camera out because my WR lenses are 50-135 and 55-300 which are too long when I was walking underneath the fall. I tried the 18-50 WR kit lens but it was not good enough or may be I have a bad copy. After reading several reviews, I was convinced that I should give this lens a try. The price is right and delivery was fast.
Summary: I own 9 compatible Pentax lenses and this one has the most personality of them all. The 18-135mm basically tries to keep a sharp center (even at longer lengths) but has soft corners at most focal lengths and apertures. This lens does not substitute the 18-55 WR kit lens because that lens has a more uniform sharpness (better corner performance) at the wide end and less distortion. It can’t substitute the 50-200 WR because the focal lengths are too different.
Summary: This lens has hardly been off my K3 since I got it. Great for a walk around lens. Doesn't rate with my Limiteds or Star lenses but very good IQ and is weather sealed. Great range and focus is fast.
Excerpt: I used to shoot a Kr, I bought a K5IIs body only, and sold the Kr, including the 18-55 kit. I normally shoot primes, but was seriously anxious about a trip to Disney with out a wide/Normal zoom. Having the 55-135 bit as an extra bonus was worth the money i spent on the lens.
Pros: very usable range, quite compact, Almost Macro capability, WR!
Cons: Yes, it is heavy, can be soft at long end, "focus ring in wrong spot" ;)
Excerpt: I should have listened to the reviews saying this lens isn't sharp. I had to see for myself I guess. It really isn't very sharp at all, especially considering the relatively high cost of this lens. Image-wise, I'd compare it quite closely to the kit 18-55mm. That is to say, contrast and color are nice, distortion is average, but sharpness and CA control are mediocre at best.
Excerpt: I purchased this lens because the Pentax kit zooms that came with my K01 had me missing shots from trying to switch them out. I looked at a lot of lenses, and finally chose this one due to it's auto-focus reliability.
Pros: Fast and reliable focusing. Quiet. Good image quality
