If weight's a concern for you, the 28-105 may be your best bet.
But it's still too early to know how good it will be.

For travel and cityscapes the 24-70 will be the most versatile. Enough wide-angle for landscapes and some architecture, intermediate focal lengths for street and documentary style, enough tele for portraits and a fast aperture for low light. The 15-30 would obviously be even better suited for landscapes and architecture, but it is not nearly as versatile as the 24-70, and also doesn't take any filters (CPL, ND etc.). The 28-105 has more tele, but sacrifices 4 precious mm of wide-angle and has a slower aperture. We cannot judge image quality yet.

Maybe get the 24-70 and add a cheap Samyang 14 f/2.8 for cityscapes?

What sort of cities? In dense urban environments with tall buildings I would tend to go fairly wide. I was in Melbourne, Australia earlier this year and I had the DA15 and DA21 on the camera (K5) most of the time. Equivalent focal lengths are 22 to about 30. In a city that has lower buildings and is more open, a longer lens might suit you better. You may be best served with the 24-70 if you can afford it; the 28-105 will be for those who need an all purpose lens and can't afford the fast, high end stuff once they've paid a whole bundle for the camera.

Go for the 24-70mm. It's the perfect walkaround lens if you already have a 70-200mm.

Maybe keep your K5 or K3? K1 is a small FF camera, but still bigger and heavier than K5/3. And the "new" FF zoom lenses are much bigger and heavier. K5 is great for travel and street shot

I think a lot of people are sitting around trying to make that same decision. Logically the 24-70 should be first as it covers the mid-range of useful focal lengths. But it is heavy, and if the 28-105 turns out very good that might be a lighter weight alternative that is less expensive as well. The 15-30 at least for me can wait a bit, but something in middle is required. But which one???

Come on Pentax Forums we need an exhaustive review of the 24-70 and 28-105 with comparisons to existing alternatives like the 28-70 f/2.8, 28-70 f/4, 24-90, and 28-105 f/3.2-5.6

It depends why you bought a full frame camera, if that's to improve where apsc is weak, that would be for wide angle, hence the DFA15-30; for longer focal length you'll have no problem covering then with your existing lenses and apsc body or with your k-1 in crop mode. Or, if you wanted to switch to full frame for most of your photographs, then you could know the range of 35mm equivalent focal length that would be the most useful for you on the k-1.

I was in Rome a few weeks ago for business and brought my K01 and 16-50 instead of the little Panasonic compact I usually have on trips. It was a good choice. Pictures were great, and it was wonderful having the 24mm equivalent field of view.

I would go with the 24-70, but I'd also probably throw my M135f3.5 or 200mmf4 in the bag for good measure...

I don't know which of the mid range lenses you have but if you have something in the 70-90mm prime range you can use that for portraits and get the 15-30 for architecture, landscape, and a wide walk around. If you don't mind a manual focus prime a good option might be an A 20mm f/2.8. Just my $0.02 (18 pt).

Based on what you're saying the 24-70 looks perfect for you.

My advice is, hold off on your decision until the PF jury is back with a verdict on the 28-105. If it gets the thumbs up it's a lot cheaper and lighter and as you say, the 70-200 stays mainly in your bag.

The K-1 lens lab, with demo shots, is up - and germane to the above, one of the company's photographers went out and did this with it.

I hope they will add proper images soon, because what's up there right now is partly useless. Have a look at the image taken with the 40 f/2.8 XS - f/9, 20 sec., ISO 800 (?!?!), exposure compensation -1, totally underexposed and with greatly reduced resolution. That is beyond useless.
