My understanding is the E-M5 won't be able to give focus conformation with
a manual focus lens, as that is principally impossible using only contrast
AF. Contrast AF is based on selecting the 'best' sharpness (contrast!)
after moving the focus very fast around the point the camera assumes you
want to focus on, in a camera controlled way. No MF lens can be controlled
like that.
Maybe an E-M1 with a chipped 43 adapter could focus confirm (since it has
the phase AF needed for it on sensor), but I can't tell you. Any E-M1
owners on the list?
