I have a Minolta 7D digital SLR.\n\nWhen I use the camera after it has been idle for a couple of days or\nmore, the first photo I shoot usually doesn't take. The shutter\nfires and the camera automatically turns itself off. The picture taken\nis either all black or almost all black.\n\nAfter that, I turn the camera on again and everything is fine.\n\nThe camera is 15 months old. It didn't exhibit this behavior when I\nfirst got it. It happens with both batteries that I have even when\nthey are fully charged. I have sent it into Minolta (and now Sony)\ntwice for repair with no improvement. Customer support tells me they\nhave never seen this before.\n\nDoes anyone know if this is a common problem or do I just have some\nkind of dud?\n\nThanks in advance.
