I think they have just about all the focal lengths covered with excellent lenses.
But people seem to really like the size and weight of the pancake lenses.

People is forgetting that with today's technology APS-C size reached it's limits, what happens tomorrow I don't know, but I always feel safer when I purchase full frame lenses. What's next after K-7? Another APS-C camera? More pixels jammed into a same size? Tighter Pixel density is enemy of the IQ, because of diffraction problem. In case for who not aware yet the problem:

Diffraction Limited Photography: Pixel Size, Aperture and Airy Disks

Thats why FF 12MP Nikon D700 IQ especially Dynamic range is so good.

Personally I won't purchase no DA lens anymore, so my first recommendation to Pentax would be an FF 16-45* mm with same or better quality than 16-45 DA.

Also FF 50-200* or at least 50-135* angles would be nice too. (Noticed the "*"s? )

Best wishes to all.
Can.

DA Ltd 14/f4 WR
DA Ltd 30/f1.7 WR
DA Ltd 85/f1.8 WR
DA Ltd 135/f2 WR

DA* 16-50/f2.8 IZ -revised version with better corner sharpness, less CA, and internal zoom (aka DA* 50-135)
DA* 80-210/f2.8 SDM IZ -sports lens, 50-135/f2.8 isn't long enough and 200/f2.8 doesn't offer enough versitility for some situations. Internal zoom.
DA* 18-85/f4 SDM IZ -as a walk-around, I'd sometimes prefer a bit of extra reach than a 2.8 aperture. Internal zoom.

I think weathersealing and some faster apertures combined with the sensational build quality and IQ of the DA Ltd lenses would be awesome.

Internal zoom is awesome, as anyone who's used the 50-135 would say

A 24 or 35mm tilt/shift.
