Hello there, new to the forum. I just bought a D500 to hopefully shoot better, less noisy pictures at the Friday night football games. I did a pre-game comparison with the cameras and found the noise at 6400 and 12800 to be close to the same, but the shutter speed is much higher on the D500 for the same exposure. I shot a scene at f8 and 12800 and the shutter speed was 1/1250 on the D810 and 1/2000 on the D500. this should allow me to shoot at a faster speed, with more reach and twice the burst speed. Looks like a good deal! I also noticed the auto white balance is consistanty warmer on the D500.
