Hi, I've got a new Nikon D610 and a 70-200 mm lens that I've been using for the past couple of months. I've not had any problems what-so-ever until today. Went to shoot - nothing fast - just a shot here and there and then it won't shoot at all. It just says r13 and flashes. I've read that it's something to do with the buffer but I've shot fast sports events and NEVER had it do this. And then it wouldn't turn off. Maybe because it was busy? I don't know. I tried to turn it off because it wouldn't stop blinking r13.
Do I need to return my camera?
