First of all, I have used a D500 for merely a few days (more like 3, 4 days). Therefore my experience with it is still quite limited. The one feature that impresses me most is the new AF module, the Multi-CAM 20000. All of a sudden my "in focus" percentage for birds in flight is really high. By all means it is not perfect, as I am still getting some occasional out-of-focus blur images, but the keeper rate is much higher now, an experience I did not have even with the D3S and D4S. I got great AF with both an f4 AF-S supertele prime and the 200-500mm/f5.6 AF-S VR. The latter is a rather slow zoom and can struggle under dimmer light or back lit situations. Nikon has moved around the controls. I really like the fact that the ISO button is now on the right side, next to the shutter release. It is now very easy to use the right index finger to hold down the ISO button and use the thumb and middle finger to rotate the main and sub-command dials, respectively. I use auto-ISO a lot. Therefore, it is now very easy to switch that on and off with the middle finger, or use the thumb to change ISO, all with only the right hand. However, I find it a bit strange that the exposure mode (S, P, A, M) button and the metering mode (matrix, spot, center weighted) button are now on the left side. It is going to take some time to get used to the change. Overall I prefer this higher-end control (D300, D700, D800 and D810) from Nikon. Unlike the D7000 series, D600/D610 and D750 where the ISO and QAUL (RAW/Jpeg) controls are on the left side of the back, where it is somewhat easy to accidentally change the ISO or RAW/Jpeg unintentionally. For action photography, having 10 fps is definitely a plus. Similar to the Canon 7D Mark II, the D500 is not laud even at 10 fps. I also don't feel that there is excessive vibration as the mirror is bouncing rapidly. I tend to use a high shutter speed for action, like 1/1000 sec or higher. Therefore, mirror vibration is not a major concern. As a number of D500 owners have reported, battery consumption seems high. However, in my case I am also using the GP-1 GPS unit a lot just to make sure that it is functioning properly. I am sure that the GPS is contributing to the battery consumption in a major way. Therefore, it is hard for me to tell in this early stage what the net effect from the D500 battery consumption is, but the D500 does seem to go through batteries much faster than the D800, D750, and D7200. A few months ago when I played with a pre-production D500 at a Nikon event, I found the true RAW buffer rather shallow. Fortunately, that is not the case with a production D500. If you capture 14-bit RAW, the buffer size is 29 frames. It increases to 37 frames with 12-bit RAW. Obviously the D500 writes faster to an XQD card or UHS-II SD, but even with a 95MB/sec UHS-1 card, the D500 can write about 4 frames per second such that you can easily capture 40+ frames before the D500 slows down. At least to me, that is more than sufficient in most action situations. I understand that a number of members here also have the D500. It would be great to hear from their different perspective.
