And everyone else, thanks for the info... glad I asked about this lense. Perhaps the Pentax 17-70 might be a better selection when buying the camera.
Thanks again.

Hi Ned,
No, the 18-200mm is not a very sharp lens. It also suffers from vignetting in the wide end.
Also, be aware of the APS-C sensor crop factor compared to your MZ film camera.
The effect is that a lens on your MZ becomes 1.5x the length on a K-7.
Therefore a 16mm lens on a K-7 works like a 16x1.5=24mm on a MZ, or your 28-80mm will work like 42-120mm on your future K-7.
The 16-45mm lens is very sharp, also the 17-70mm and the 16-50mm are very good lenses.
Recently Pentax stopped the 16-45mm production, however you may find some specimen available for not so much money.
