infinity for old Legacy lenses?

Hi all.

Just wondering if using Canon FD, Leica M, Konica, Minolta MD and the like on m43 bodies will keep infinity focus without the need for corrector lenses in the adaptors?

I use Canon and Oly DSLR and they are pretty good for using old OM's, Nikkors, M42 and PK lenses but lose infinity for the other lenses.
