Exposure Program
The exposure program for programmed auto is shown in the following graph:
F (lens focal length) ≤ 55 mm 55mm < F ≤ 135 mm
135 mm < F

The maximum and minimum values for EV vary with ISO sensitivity; the above graph assumes an ISO sensitivity of ISO 200 equivalent. When matrix metering is used, values over 171/3 EV are reduced to 171/3 EV.
