Walk around lens - 18-135/18-250?

Looking for a nice walk around lens to sit on my K5 II.

Thinking of either the 18-135 WR or new 2012 Sigma 18-250.

Sigma seems to actually have decent reviews, which is unlike a super zoom!

Think the pentax model has HSM too, which is a bonus.

I know IQ on superzooms can be questionable, but will have some primes for high IQ shots!

Need WR? Go with the Pentax. Otherwise get the Sigma

If I were you I would go with the WR 18~135 lens, a couple of reasons- WR! you want a good walk around lens and you never know when you will be walking around in the rain or wet area, so that is a "no brainer", you have a WR camera! what use is it if you cannot utilize that feature?. Two- it is most likely a lighter lens than the Sigma, when you are walking around, you want to go light as possible, but then again I walk around with my set up along with the battery grip on it as well, and that really isn't that heavy to me. Three- this lens also has something the Sigma doesn't, and that is quick shift, I though I would never use that feature but I was wrong, I find I use it a lot, and when I use other lenses without it, it sux.
Hands down, I would definitely go with the Pentax 18-135mm YMMV

I have boththe DA18-135WR and the older DA18-250mm. If I was on the maket for a new all-around zoom, I woul go for the DA18-135mm for WR and Qucikshift.

On the other ahnd, if you are considering some 2nd hand lens,the Tamron/DA18-250mm is worth condiring. Manusfactured by Tamron, and rebadged by Pentax, the Tamron 18-250mm version tends to be cheaper. Adorama has one for $349: Used Tamron 18-250 Xrdi-ii Ld F/pxaf.

Hope that the comment may help.

The new Sigma 18-250mm Macro has excellent reviews--the Pentax 18-135, so-so. For IQ, get the Sigma. (I actually ordered one from BH, but they didn't have it in stock, and I wanted it for a trip to Spain. I ended up canceling the order--I think I'll get the new version of the Sigma 17-70 instead, when it comes out.) For WR, get the Pentax.

So will the Sigma have as good IQ as the Pentax?

Its tricky, as WR would be great, but the longer reach would be great when I fo on holiday.

The reason to have a super-zoom is the focal length, not IQ. So, I'd get the one with the bigger range.

The 18-135 has a DC motor, not HSM (or SDM).

I find the 18-135 ideal as my walk-around lens, but I'm not much of a telephoto shooter.

As for those who question the IQ of the 18-135, if you could see the calendars, photo books, and 8x10 & larger prints that I have made, you might change your mind about this lens.

How quick and noisy is the 18-135? Only had experience with 18-55/50-200 WR lenses and they were a bit slow and noisy.

Just about decision time. Not found anywhere local to try the 18-250, so sadly got to base my purchase on reviews. used the 18-135 and was impressed at the speed and weight on the K5 II.

I have been looking in Australia for a travel lens for some time and have priced the Pentax 18-270 the 18-135 and the Sigma 18-250 Macro all these lens are distributed by C R Kennedy I checked as many reviews as I could and in the end decided on the Sigma.

Main reasons 1) Price in Australia the Sigma is cheaper by a considerable margin (Got it for 549.00)
2) Warranty 2 years for the Sigma 1 for the Pentax
3) Of all the reviews Sigma is mentioned often as the best superzoon available

I did think seriously about the 18-135 because of the WR but I have a 18-55 WR and I do use the extra lengths quite a lot so in the end the decision wasn't that hard to make. There is about a 3 Week wait for the Sigma at present apparently the initial stock sold out in only a few days so I have to wait for the next shipment.
It will be interesting to see if it lives up to the reviews
