Thanks mate, much appreciated with the gaffer tape. I had taken some Dolphin pictures this morning then went for breakfast whilst there my camera started taking pictures on its own, then started going through different program modes when I shoot in manual, tried removing battery grip and using single battery , still the same every time I powered it up. Its definitely not very well. I've tried google for advice with no joy, since then I've spoken to Cambrian photography who told me that its happened to two other people that they know about so unfortunately its back to Canon mate
