I am very bummed. I am on vacation at the beach and have been taking lots of photos with my G5. I have tried to be very careful and keep the camera dry and sand at bay. Then today, my G5 went a bit nuts. It is acting like I am changing settings, but I am not. I have tried everything I can think of to fix the problem with no success. I really love my G5 and was not planning on buying another camera right now. But I have to have a camera. I am thinking about the new G7, but I am also considering a GH3. I think I would like the weather sealing of the GH3 for my trips to the beach and such. But I like the G form factor. The GH3 is actually a bit cheaper right now at B&H. In use, which one would you guys recommend?
