Question about the PL 45mm.

Hi Bill,
When set to full the focus range is 0.15 m (0.5 feet) to infinity, when set to limit the focus range is 0.5 m (1.64 feet) to infinity.
Thus the lens will focus quicker when set to limit and this would be the choice for street photography, portraiture and the like.
My own experience when using it for close up macro is that it can be useful to actually fine tune the auto focusing with a final manual adjustment to ensure accurate focusing. This would probably not apply when used in non macro mode, the auto focus will almost certainly be sufficiently accurate.

VG price for that lens Bill

I mostly use it in Full mode ... the AF is not infallible I have used manual, one trick is to AF on a an easy target to set distance then AF on the actual object so AF has less work.

The PL45 gets confused with locking onto slender objects at times or having to AF lock close after focusing previously at a far distance.
Depends too on the object type etc.

DPR review did criticize the AF but in practice it gets the job done and is a superb optic.

The OLy AF + MF setting is an advantage at times a great feature on the Pens

Contrast AF from my experience is not as good as Phase detect AF (DSLR)
