Very strange marketing with the new motor. This should really be an excllent focusing system like many have demanded for some time now, but you'd hardly know it from the material. DC doesn't really mean much (Direct Current motor does not exactly sound awesome, like Silent Wave Motor), and worse the cheaper Canon AF motor is also called DC motor, which could lead to confusion. This was a good chance to call it something like MD (magnetic drive) that would sound impressive as well. And trumpet it more, "a lens with a revoltuionary new patented focusing motor that alows silent, instant, and accurate autfocus with advanced magnetic field technology, while allowing full-time manual control". But instead the DC acronym is just stuck into the name and the press release mentions SDM; you'd never know it was something new and different, let alone what the benefits are
That's Pentax!

This could be a good lens for my wife to use when we go shooting together. She doesn't ever want to have to change lenses. She used to have a DA18-250 and that's really not a bad lens for what it is, but the excessive zoom creep makes it feel cheap, IMO. I sold it and told her she can use my DA* zooms. So if this turns out to be better IQ -wise than the 18-250 and isn't creepy, then it could be a winner. Then I don't have to worry about her using a lens that I may need.

Well, let's wait till the dust has settled and some good assessments of this lens's qualities are available. It's a very useful focal range. I'd certainly be up for a copy if the quality is good and the price is right. No one is going to buy this or any similar lens for funny money so I'd guess its street price will settle down soon enough, whatever the rumours may be today.

799,- € is a big price, but the datasheet looks very promising. I can't imagine a better traveller lens for the K5 and K7. 18-55 WR and 50-200 WR as a set is a bad compromise if you are on tour. The DA* 16-50 and DA* 50-135 have a fine IQ for zoom lenses, but we all heard about few/some problems with their SDM.

Pentax made all things right this time. They tried another motor-concept when they heard about the problems with SDM and offer us one lens instead a set. F3.5-5.6 is no world record, but imagine the price of a 18-135mm F2.8 ED AL[IF] WR DC. Only a small elite could afford it. I can live with f3.5-5.6, as long as IQ is fair for a zoom lens. The lens is no beauty, but I am out with my cam to shot pictures, not to win a contest: "who have the lens with the most golden rings".

In my opinion THIS lens will be the main reason for the success of the K5. It's great to get both as a Kit.

Anyone knows more, if the 13 elements / 11 groups is an unique construction?

It certainly is not the same construction as the Tokina.

About the focus motor: Yes, unfortunate name choice. But many of you are jumping to conclusions regarding it's qualities. Pentax certainly say it is fast and quiet, but maybe it's only moderately fast and not completely silent. Maybe it's not supposed to be the greatest focus motor of all time, but simply something quieter than in-body motor, but "below" SDM.

So much for this being affordable.

I would agree with fzwo. I have a feeling that this motor is just a micro motor like in the old SDM but hopefully without the reliability issues. I am thinking (and hoping) that the SDM with the magnetic drive (like in the patents) will come out, but on DA* lenses as potentially an SDM II. Hopefully we will see a 50-135 DA* but with the magnetic drive focus.

I believe the price is comparable to other manufacturers. The better quality superzooms are not inexpensive. There are inexpensive off-brand superzooms and the WR kit lenses for those who don't want to spend this much on a travel zoom. Personally I'd rather pay more and get more.

799 € for a zoom lens that is as slow as 5.6 at 135mm? This isn't fun at all.
Is slow and expensive the new motto?

So can someone explain the difference between SDM and DC for me? The benefits are what?

The main point would be that the rings are in the wrong order.
This is a no-go for me.

But: Never say never ...
If this was your only zoom lens (plus a nice bunch of limiteds) i don't think a person would have to much problem learning. Most people hold the end of the lens for support anyway and its rather annoying when you autofocus with your fingers on the focus ring!

Sigma also recently reversed their 70-200 focus/zoom ring order. Must be the fashion.

Let me say that I don't mind the new lens styling except the garish green ring just has to go. We've been putting up with this for far too long. No arbitrary colours on my lenses please!

I like the green ring, but I hate the text.
