G5 with old oly OM-1 lenses?

Many thanks to all for the valuable info, I appreciate it very much. It answers my concern about aperture and assures me that the combination m43 + legacy lenses works very well. I'll finally be able to get nice blurred backgrounds! Manual focusing with video is an interesting idea too.

Thanks also for informing me that the OM-D buzzing problem was only a minor issue. Both the OM-D and G5 owners seem to like their camera a lot, good news for me!

Cheers,

Paul
