Because the microphone input is 2.5mm most mics are 3.5mm. So I use this to connect my wireless microphone to: I had the camera connected to this exact tripod/video head: I was on the roof filming so as we went down on the ladder I passed the camera which was anchored to the tripod to my subject who went ahead of me. I know he held the camera with the camera strap when I wasn't looking as I went down the ladder. The weight of the camera/tripod/video head was too much for the 2.5mm to 3.5mm adapter and the strap torqued it out of the plug and bent the jack. I came down to find the adapter hanging outside of the camera.....I put it back in and there was no drag or 'click' as it went in. I've tested another exact adapter but the GH2 doesn't seem to recognize that there's anything in the mic input plug. Is this fixable or is it cheaper to just purchase a new/used body? I'm assuming this connection is part of a main circuit board which is tough to fix.... Any advice would be great before I spend money shipping the camera across the country to get diagnosed. During the shoot I had no choice but to purchase a new camera so I went with a Canon T4i with the 18-135mm lens. Gawd this thing is heavy/big compared to my broken GH2 and nowhere near the same video sharpness. But images seem to look marginally better than my GX1/GH2.
