I am considering buying the Olympus 4/3 50mm macro lens plus the 4/3 to micro 4/3 adapter for my G1. The auto-exposure mode is supposed to work but the lens can only be used in manual focus mode. So I'm wondering if the focus assist works with the lens and adapter combination. That is, when you turn the focus ring the camera magnifies the view so you can better see when the subject is in focus. Or will I have to manually invoke the focus assist as I do with my Nikon lens plus adapter? Has anyone used the 4/3 adapter with a lens that doesn't support the auto-focus mode?
