Hi, i have a Nikon D1x that i was lent by a press group but will have to give it back soon but it is now failing. The problem is that it turns on and everything works fine except the fact that it doesn't do what it should and wont take the bloody shot. It works perfectly fine for about 1 hour after charging but then starts failing with the battery still supposedly fully charged, the problem started occurring after an extremely cold day and it is just a copy battery not an original Nikon, could it be the battery or is it more likely to be something faulty with the camera. by the way it has never been dropped while i have had it and has always been looked after properly so personally i doubt this, just thought i would be better asking for a few other peoples opinions, cheers
