Quite interested in snagging a GH3 body for video but would really like to use my lovely Pentax primes. Do you guys have any specific recommendations as far as which adapter to get? There is a very pricey Voigtlander adapter that runs for about $180 but I haven't seen any reviews on it anywhere. I'd be willing to consider that one if it's really worth it. I know there are much cheaper options out there but I also know that you often get what you pay for so any guidance in this area would be much appreciated.
