The lens roadmap showed this as being the large diameter standard zoom, and the more likely lens from the roadmap to be used as the FF kit lens will be the 28-105mm standard zoom.
Unless it's a 24-105 Standard Zoom.

It is the one lens we know won't be a rebadged Tamron...

As many have stated above, the current leaked retail price is 160,000 Yen, which comes to about $1335, which is actually awfully close to what B+H is listing as the retail for the Tamron for .
226 800 Yen - 1880 USD

The Tamron 15-30 is reputed to be even better. Some claim it's as good as the Nikkor 14-24. I don't happen to believe that's true (the Nikkor has richer color rendition), but again, adding Pentax's HD coatings could take this lens to the next level and allow it to hold it's own with the highly regarded Nikkor.
If pentax releases a 15-30 with WR and HD coatings, that will be the landscape photographer's dream. I was hoping that Pentax and Tamron were working together. This is total speculation, but I wonder if the new Tamron 35 and 45mm prime will be rebadged for K mount.

If we see similar rebates as to what we are seeing with the Tamron, the street price will likely be closer to $1100. Also, as others have stated, it's significantly cheaper than the Canon and Nikon equivalent zooms.

Me, I've got the FA* 28-70mm 2.8 sitting on my desk as I write this, so unless I really want the weather sealing or the new D-FA is a step up in image quality, I'm not too concerned either way.
I like the weather sealing, but the big thing for me would be having 24mm versus 28mm. I can deal better with having less length as long as the standard lens is wide enough.

I assume many landscape photographers will have a rather rough wake-up when they realise it doesn't accept filters

Ummm...Neither does the Nikon 14-24, and many landscape photographers swear by that lens.

If you had actually read the thread above (or even the very message you quoted), you would have seen the expected retail price has been updated to 160,000 Yen.
My point stands.

Just for reference, the comparable Canon DOES have a filter thread (albeit 82mm), so it is possible to create an UWA f2.8 zoom with filter threads. And yes, some of us use CPLs on our wide angle lenses at times. Last I checked, there isn't a good enough software fix for that. Guess we'll have to tape a polarizer over the lens?

As I understand it, SDM is a motor and gear system while DC is a ring motor type system, so, no, I really would prefer DC. IN fact, just using my 18-135 DC compared to my DA*60-250, I'd be really reluctant to buy another SDM lens, it's not terrible for speed, but it's also not $1300 great either. But then I also have an FA 35-80 and an DA-J 18-35. So simply stated, if I want a lens with a geared lens, I have two already. This will be DC and fast focusing, or a lot of us are going to take a pass.

And people were already always asking if pentax lenses were just tamron rebadges... Well, I never wanted this one anyway, neither the 15-35 f/2.8: bring forth the DFA 20mm f/3.5 LTD, damnit!

Even if the "SDM" is identical to the well regarded system used in the Tamron badged equivalent (which seems extremely likely given the minimal exterior differences)?

SDM is just an umbrella term for a series of different motors used in different Pentax lenses. There is a good chance new Pentax lenses will have better (and more reliable) SDM than the older ones. In addition to that, this lens will probably have a Tamron SDM.

About the USD (SDM) in the Tamron ePhotozine said:

"As this lens incorporates Tamron's USD silent focusing motor, focusing is reasonably quick and very accurate. Focusing speeds may not be up to the speeds of Nikon and Canon equivalents, but they are not too far behind in all but the darkest conditions."

DPReview said:

"It's pretty quick and responsive, although in side-by-side testing on the same camera bodies it's clearly not quite as lightning-fast as the Canon equivalent. We've seen no obvious systematic problems with focus accuracy on any of the cameras we've used for testing, ranging from the entry-level EOS 650D, through the enthusiast-orientated EOS 60D, to the semi-pro EOS 6D."

So it seems to be reasonably quick, and if it is not far away from Canon and Nikon, it will be at least as fast as the fastest Pentax lenses.

TAMRON | SP 70-300mm F/4-5.6 Di VC USD for Canon, Nikon / SP 70-300mm F/4-5.6 Di USD for Sony [Model A005] What's USD? it's this type. Totally different from Old Pentax SDM in the 16-50 50-135 and 60-250
