HI folks...i have 2 d80's...occasionally i have a problem that when i press the shutter release, nothing happens., then works again in a few seconds.....seems completely random. I do not get an error message and i would not think that it is a capture problem, as i am not shooting quickly. i have tried using faster cards, no difference. With the talk of failing shutters, i have to wonder, is this the prelude to a dead shuttter? happens on both cameras, and both cameras are under a year old with high use. happens on camera with full or nearly dead battery too. any ideas? what do you think?
