I recently bought a used D800 from a Nikon dealer and returned it after only a few weeks of using it. I am anxiously awaiting my brand new D800 as I am typing this. One of the problems which I had with the used camera body was a constant "ERR" message which kept flashing. When the message would flash my image would be completely blown out. I was using two different batteries with the used unit, one was Nikon and the other was an off brand. Do you think that the off brand battery played a part in the Err message appearing? The message would appear regardless of which battery I had in the camera at the time and also regardless of which CF card I was using as well. My question is do you guys use off brand batteries? and do you think that I will be alright using the off brand in my new body or should I stick with Nikon OEM?
The symptoms suggest a shutter or aperture index arm problem. If it happened on one lens I would guess the aperture tab on the lens. If on more than one lens the camera was surely at fault and not related to the battery in either case. Good luck and have fun with the best DSLR camera on the planet! Stan St Petersburg Russia
I agree with the suggestions that the used D800 had a mechanical or electronic problem and you wisely returned it. But on batteries, I have used nothing but Nikon brand batteries from reputable dealers. I read how people use other brands, but figure it's just risky to use the others. I'd imagine this would also void a warranty if you had a battery-related problem. My thinking is -- why spend nearly $3k on a camera and then scramble to save $20 on an accessory that goes inside and powers the camera?
