My Nikon D7000 is now 6 months old, all has been well until a few weeks ago, one of two things seem to happen all the time. I take a few shoots and all is OK, then, randomly, I shoot a few more, go to check my LCD Screen and there is no recording of the images just taken, worse, it now won't show me the shots I took earlier which I have already seen.
The second, which its doing now with alarming regularity, it will shoot a few pictures, then I go to shoot again and I can't depress the shoot button(shutter release), the readout says there is no memory card detected, to resolve both these issues, I have to switch the camera off, take out the memory card, put it back in and start again, this morning it was taking no more than 3 or 4 pictures before freezing, I am using genuine Nikon batteries and have just invested in 2, 32GB Sandisk cards, thinking I had a faulty card before, but no!
The worst of this is I have just started shooting weddings, can you imagine the stress of not being able to trust your equipment at such an event!
