My GH2 continues to present two odd behaviors. It does neither continuously but does both too frequently. I'm trying to figure out if the camera has an issue or if I'm doing something wrong. The first problem is with auto focus in the 14-140 lens. About one in ten shots the lens does not auto focus. It just sits there in out of focus mode; the camera will take a picure this way even though focus priority is set to ON. I have noticed that I am frequently hitting one of the back panel buttons inadvertenly, though ISO and white balance are pretty obvious when the pop up in the viewfinder. I'm wondering if I am creating the problem by bumping something else, though I don't know what that could be that I wouldn't recognize it. The problem can be cleard by cycling the auto focus swith from AFS to MF and back. The second problem is the light meter freezing in 'shoot without lens' mode. This happens quite frequently when I'm using a manual lens in aperature priority mode. This is manafested by the shutter speed staying fixed at the speed of the last shot. The problem is cleared by changing the shooting mode from A to P and back. This seems to happen most frequently after I've aimed the camera towards a bright light souce. Since I'm typically using a fast lens wide open in this mode, I'm wondering if there may be some kind of safety sensor in there that senses over exposure and locks something in the imager. I have written twice to the company I purchased the camera from but so far they have not responded. The problems are not so bad that I would consider the camera broken, but they are a hassle and don't seem right to me. Has anyone else observed similar behavior?
