The shutter and aperture are electrically controlled and actually have an infinite (well *almost* infinite!) range of possible settings. The camera only *displays* the standard values, choosing the ones that are closest to the shutter speed and aperture that the camera is really using. Even with mechanical cameras like the K1000 you could get "in-between" shutter speeds by balancing the shutter speed dial between settings. -- Mark Roberts Photography and writing www.robertstech.com
