But are any of them power zoom lenses? I think most of the IF lenses
replaced older power zoom designs. The 100-300 power zoom doesn't
change size at all when zooming, only when focusing. Others, like the
28-105 power zoom, can change size nearly as much from close focusing
as they can from zooming. It's just too bad half this feature is lost
on the MZ-S, but it is a minor complaint, at best.

Strange on such a high spec body, Pentax eh :)
Not if you assume it's going to be used with IF lenses ...
With most of my lenses the change of length with focus isn't
all that great (even discounting the IF examples). But the
change of length with zoom is much, much larger.
