I like to think of "do everything" zooms the same way I think of "Asian Fusion" restaurants - they try to "do everything" and end up doing it all poorly. Zooms beyond a 3:1 ratio introduce too many optical compromises to be good performers, so only those too lazy to carry a few lenses to cover the same range, and who don't give a crap about their image quality, should buy them. I don't like mediocre food, and don't like mediocre lenses, either.
I, as a lazy shooter with many lenses, think I am the right person to reply here....
First of all , any zoom is a compromise. But there are usually two reasons and in this case even tree reasons why a superzoom has it's uses and aybe you shoudl try them a few times to appreciate their versatility....

1- no need for multiple lenses. this may ofcourse depend on your style of shooting. if you just wat to go out for a ride or a walk, without anything special to shoot in mind, just that ride or walk, you might not want to lug a big bag with lenses along. Just one camera and one lens. Now I know prime challenges your skills but that is not the objective on such an outing.
2- when you go to shoot something the smaller zooms or primes are too limited to use in fast changing circumstances, expecially when distance chnages a lot. yo miss a lot of action if you need to change lenses frequently.
3- as the 18-135 is a WR lens you need not worry about having to change lenses often in adverse conditions.

Janneman, I'm with you here - as long as this doesn't turn out to be a dud, you can sign me up for one. It's the right range and size for travel, and the WR gives added peace of mind.

As for the slow speed at the long end, that is offset by the superior high-ISO performance of the new bodies. But it'll leave enough room in your bag for you to pack a fast prime for the really low light stuff.

If this lens is even half-decent, it'll be a great walkaround and travel lens.

I think a very nice travel set could be this lens plus a few limiteds. Use the zoom for the casual shots, the limiteds when you have more time for photography. I already have the DA70 and the DA35, but if I buy this lens and leave the DA16-45 at home, it will be very tempting to add the DA15 for the wide end.

I started with the K10D and the Tamron 18-250mm. It was a great fun but IQ was a mixed bag. The Tamron was unexpectedly sharp, well most of the time and you had to stop down to f8-f11 to get good borders. After 100-150mm it also started to soften. I finally sold it and never really regretted it (especially after I run some statistics that showed that I used it mostly at 18mm, its weak point).

But this new 18-135mm gets my attention. Firstly it will be much better built than the Tamron (DC, WR, Quick Shift) and I no guess zoom creeping like the Tamron (that's why it has a zoom lock. I never had that on any Pentax zoom I used (55-300, 18-55, 16-50, 12-24, 80-320, 50-135, 10-17, ... ). Secondly the range is more realistic so I expect better general performance.

CA and lens distortion being correctable by software (or by the camera) it's no big deal anymore. Thus the main characteristic that we will have to look for is sharpness. Especially in the borders, this is generally the weak point.

One immediate disappointment about the new lens is the lack of distance markings. But it maybe understandable since the focus ring doesn't move. (DA* lenses offer a window to see the markings though).

Another one is the conservative range. A 15-85mm would have been more useful to me.

But in the end if the IQ is decent and the lens not too expensive, I'll get one.

pentax 16-50mm is 3.125:1
From what I ve seen people are satisfied with the 55-300mm (5.46:1)
On the sony side the minolta 28-135mm f4-4.5 (4.82:1) is sharper than its zeiss and G lens counterpart.

the 18-250mm (13.89:1) is a good enough performer for some pros.

I m still unsure where the bigma stands though.



A WR 18-135mm with a WR 55-300mm (I know it doesnt exist) paired with a K5 (the high iso balancing the speed of the lens) would be a great lightweight combination.

I'm of the same mind. So much in fact that the 16-45 is gone, and so will the 18-55 WR when I get my mitts on this lens. Carrying the 15mm, 21mm, 40mm and if needed the 55-300 and AF-360 means a pretty complete bag! (since I shoot wider rather than portraits).
I'm looking forward to do some snow shoeing this winter, and K-7 and 18-135mm will mean a ~1.1kg rig to carry.

I came back from my last trip with the K-x + DA 18-250 and I was disappointed in too many photos. Damn the convenience, the big zoom has to go. It's much better suited to my wife's K100DS, which is good for her because she loves it. Not so good for me, because I can't recoup any dough.

I have high hopes for the 18-135. The size, walkaround range, WR and silent focus are strong pulls, but I need better IQ than the kit lenses or it's a no-go. If the 18-135 is good enough, it will push the 16-45 to my secondary kit, which will cause me to redesign both kits. This could be an expensive proposition.

Fortunately I don't feel the need to buy a camera this year. My K20D and K-x are more than enough.

I would really like to love a lens in this range. (Let the truth be known, another mm or two at the wide end might be even more lovable.) However, every 18-135ish I've seen is no better in any way than the 18-250ish lenses. I'd be up for something to replace the kit lens as a travel lens (backing up primes). The new 18-135 is an inch shorter and just a tad lighter than my DA17-70, and that may be just enough difference to have it fit into my travel bag.

That has been my observation as well. I'm hoping that Pentax pulled off a coup, bringing it into the next level of performance.
