Yes, the lenses with FT-M function can do AF+MF, work like Olympus but they
are mecahnical, most of the more expensive lenses have this feature. The
manual focus with these lenses are not as smooth as our old OM lenses or the
DZ lenses. The electronic focus on the DZ lenses are very smooth but also
has its problem, just like the DZ50/2, the change of focus is not the same
with clockwise and anti-clockwise direction.
