I just brought a D2 but I have a problem. When I turn on the D2 without the SD card all the function is good but once I inserted the SD card the shutter speed button is out of control. When I press down the shutter speed button it take around 10-15 seconds to shoot a photo and each 10-15 seconds it will automatically shoot another photo. And so wired when I look at the photo info in my PC it shows it is took by D3 not D2 but every time I reboot the camera it will allow me to press the shutter speed button again ... here is photo that I check my firmware in D2 ... anyone know how to fix it ?
