realy liking the GH3
Playing around the kitchen with an egg and off camera flash, the 12 - 35 lens is sweet too. The handling and controls are excellent.
Did you control the off camera flash wirelessly? Or via cable plugged into the GH3?
If wirelessly, does the on camera flash have to operate? Seems that way from the manual though I may well be mis-reading it.
I used pocket wizard 2 on hotshoe, have not tried sync port yet, but should work ok.
I usually dont use on camera flash, just set flash to forced on, and leave flash in down position. It wont fire on camera flash. Same as GH2 protocol.
One problem with off camera flash on GH2 and GH3, is that you can't use the on camera flash to trigger an optical slave. As the on camera flash does a pre trigger flash that set off slaves too early.
radio triggers work excellently on GH2 and GH3
