With my old D80, if you set up bracketing and held down the button, it would shoot the bracketed shots as fast as it could, and then stop.
I can find no setting on my D7500 that produces this same behavior. It either fires the shots one at a time or doesn't stop when the bracketing is done. On continuous/slow, I can almost always count it correctly, but not every time.
Am I missing something, or isn't this possible?
