Hey guys! I have been using a Iscorama 2x Anamorphic lens on my Panasonic GH3 and unfortunately the image I'm getting is the 16:9 ultra wide image that just won't do for my personal taste and most peoples taste in film as well.   My question is, can I get the GH3 to shoot video in a 4:3 aspect ratio or can I at least expect a patch or an update to allow this feature? It would be very disheartening to hear that I won't be able to do this at all as I would love to continue to shoot with an anamorphic lens.    Thanks!
