Every lens posted here are considered good and are capable of producing great images.

Here are a few example of the 17-70 (v1).

Very sharp even wide open in the centre (pic 1 f/2.8, dog)

Great color depth and contrast (pic 2 f/5.6, sunset)

Great flare and ghosting control (pic 3 f/11, leaves and sun)

Great contrast and low light capability (pic 4 f/2.8, tree after dark)

Survived spray and moisture often (with care) and deals pretty good again with flare and ghosting (pic 5 f/4, old hydro dam)

Perfect example, if your pictures are like mine you want an 18-135, if you pictures are like this portrait, you want a 17-70, couldn't have said it better myself.
I should have mentioned I still pack the 18-135 first though

I use the Tamron 17-50/2.8 indoors and the Pentax DA 18-135 WR outdoors as my common walk around lenses.

Indoors I tend to shoot portraits close and wide and often need to use a flash. The Tamron excels as an APS-C go-to indoor lens.

It is is hard to beat the 18-135 WR as an outdoor walk around lens in any kind of weather. With my-K-30 it has gone to the beach in a snowstorm and the beach in Cuba in a sandstorm! No problem, no worries. Rinse, dry, and go.

If you want to see a test comparison, don't read the reviews or the conclusions, reviewers tend to trash the 18-135, even though there isn't a better super zoom available... but look at the MTF numbers available for various focal lengths. With all respect to peoples impressions, impressions often are only supported by individual biases. I really appreciates these guys who devote their time to do independent testing. And you have to understand, most of the initial reaction to the 18-135, was sticker shock, even I don't think it was worth the $700 I paid for it, but the $400 it goes for now, it's a steal.

Sigma AF 17-70mm f/2.8-4.5 DC macro - Review / Test Report - Analysis
Sigma AF 17-70mm f/2.8-4 DC HSM OS | C (Nikon) - Review / Test Report - Analysis

Pentax SMC-DA 18-135mm f/3.5-5.6 ED AL [IF] WR - Review / Lens Test - Analysis

The best score out of 2900 on a D7100 for a 17-70 @24mm i@ƒ5.6 is 2713, 2435, 2360
The best score out of 2750 on a K-5 for an 18-135 @ 24mm @ƒ5.6 is 2683, 2419, 2286
Just to understand what this means pick your favourite lens and see what it's best numbers are.. given a top score of 2750 the 18-35 at 24mm achieved 2683 centre and 2419 edge. How does your favourite lens stack up?

For example, one of the sharpest Pentax lenses, the DA 70's numbers are @ƒ4, 2706, 2473, 2370, barrel 1% to 4% better than the the DA 18-135.
The best a 31 ltd did on klaus' test, @ ƒ4.0 2563, 2345, 2198
And the stop difference is about a half stop between the 18-135 and 17-70. People seem to ignore that this lens at it's best is right up there with the best Pentax Primes, the 17-70 quite simply isn't.

Ya, I'm a bit of a fanatic about this, but, I do get really tired when people try and say the DA 18-135 isn't one of the best pieces of glass out there zoom or prime. And people say the 17-70 is sharper, really... why should I believe that? Klaus' shows me the numbers, I can see where it's strong and weak. The PF forum members don't do nearly as detailed a breakdown, and most Pentax reviewers have been prejudiced by the early reviews of the lens, that rightfully expected more of a $700 zoom. The trouble with these reviews is, they are pretty much static. Once written, no one corrects them. The price goes down, the errors they made in comparing it other less sharp zooms, etc. never get corrected, but for those willing to dig a bit deeper, there are some really impressive numbers on this zoom. It could be used as a case study to show how the social dynamic of the forum alters the perceived sharpness and reputation of a lens. While I like Adams reviews on PF forums he often has a different opinion and I do, when reviewing equipment I own, and so does Klaus at photo zone, but Klaus puts the numbers up, and if he miss judges a lens, I can go look at the numbers and readily see that he's had an error in judgement. PF forum, not so much.

Easy normhead, no one has started bashing on the 18-135 here yet But wait until the DA 70, the ltd or the fixed focal length fan clubs get here, they will want some blood and ask you to put your *pictures* where your mouth is :P

Here's a couple shots with the 18-135 with very little setup.

Hush! hush! don't wake 'em up

But I'll give you this, the 18-135 is indeed underrated since it's kind of a kit lens. And we all know that kit lenses = Evil (emphasis on sarcasm) I had one for about a month when I got my K5 (came with it)... I didn't shoot much with it (I can't find any pictures taken with it in my library) mostly because I didn't like the backward zoom/focus position and at the time I didn't need the range and my 50mm was pretty much glued to my K5. So I sold it... and got the Sigma :P ... but that's a different story.

I admit that once I joined here and saw pictures taken with it I had regrets of not giving it another chance but the Sigma has been very good to me too.

There's nothing the matter with a lens suiting you style, I'm sure for a lot of people that ƒ2.8-ƒ4 is worth more than 70mm-135mm.. just not outdoors shooters.

When I first used the 18-135 I did not get the results I saw others on here get. Then I learned the lens and am VERY happy with it. It will be one of my not going to even think about selling it lenses.

One aspect that we really love about our helios 44k-4 is the image quality that I could only describe as "creamy"
shot indoors on a really cloudy day too!


is this effect unique to these old Russian lenses? I'm sure I could just do it in post processing too...

really just trying to decide between the sigma 17-70 and pentax 18-135 WR. I'm not sure if we ever really need that zoom, though. I'm sure I will have both lenses sooner or later! My son is only 6 months now, but the zoom will come in handy for sports. And we do love the outdoors...
