If you want to get the maximum continuous shooting speed of 10 fps, you should set the camera to Ch.
The speed of “Continuous low” setting can be changed through the camera menu. Assuming that you are going to be using the camera primarily for sports and wildlife photography, you should set your camera to either “Continuous low” or “Continuous high” mode, depending on how many frames per second you want to shoot. The dial has a bunch of shooting modes like “S” (Single), “Cl, Ch” (Continuous low and Continuous high), “Q” (Quiet), “Qc” (Quiet continuous), Timer and Mup (Mirror Up).
The primary function of this rotary dial is to set your shooting mode and the buttons that sit on the top are there for making quick adjustments to image format/quality, metering, camera mode and white balance: On the top left side of the camera you will find a large dial with buttons on the top. However, in order to do 3 EV bracketing, you can only enable 5 frames of bracketing or fewer. The Nikon D500 allows bracketing up to 9 frames and up to 3 stops (EV) apart. Using the front dial will allow changing bracketing steps and the rear dial will change the number of frames shot in a bracketing sequence. It should show “0F” on the left side, which means that bracketing is inactive (the “BKT” letters should also disappear). Make sure that bracketing is turned off by holding the button and checking the top camera LCD. Right above the AF / M lever, you will find the BKT (Bracketing) button to set up bracketing on the camera. Let’s move on to other external controls. The way this is set up is explained below under the Custom Settings Menu -> Controls. This way, I can use both AF modes by pressing two different buttons. When shooting wildlife, I typically set my AF mode to Dynamic Area AF (72 points) (D 72), but keep my joystick center button to Dynamic Area AF (25 points). Once again, most of these are already explained in detail in my autofocus modes explained article, so I won’t go into too much detail here.
These settings are there for controlling the focus points that you see inside the viewfinder. Now if you rotate the front dial with your index finger while holding the same button, you will get many different options like “S”, “D 25”, “D 72”, “D 153”, “3D”, “GrP” and “Auto”. If your goal with the D500 is to mostly capture moving action, then keep the camera in AF-C autofocus mode and only switch to AF-S when needed. When you half-press the shutter button and your subject moves, the camera will re-acquire focus.
