So, the real DOF may not be shown by default so that the camera has the best focusing conditions rather than for the user per se. Other than that distinction (it is for the camera hardware to 'see' rather than for the user to) the answer is sound. Ah... actually you may have meant that the display wouldn't necessarily dim... true. | |
