I asked this question in the HPX250 forum and it was wisely suggested I ask here too, as the 3 series have been around longer. I'd like to see some examples, or hear from anyone who has worked with these cameras together. In my case I would be looking to use a GH1 or 2 for b-roll/back-up alongside an HPX250. I'd be doing very little multicam with this combination, but I'd be interested to see if anybody has worked it and how it worked out for them.
Cheers
