Hi folks... I've amassed some nice glass with my OMD and EP1 - Oly 45mm, Lumix 20mm f1.7, Oly 75mm, and an Oly 45-150 zoom. I hear different takes on native versus adapted/manual lenses for video, but this is some fast/quality glass. I'm thinking about picking up a used GH1 to play around with video. Seems like these would produce pretty good results. Should these suffice or do I need like the Nikon/Canons (I see the Nikon 50 1.4 discussed a lot)? Thanks!
