My battery (I have three and all have the same problem) isn't working properly. I've charged it and also done a refresh, no change. What happens is, the battery icon flashes, showing half full, I can take maybe 4 or 5 shots, then it won't work anymore. I can, however, still use my display image, just won't take any pictures. Any reason for this? Is it my batteries or maybe a connection/contact problem inside the camera? Or is it the camera itself? Thanks in advance.
