Exposure Program (Mode P)
The exposure program for mode P is shown in the following graph.
F (lens focal length) ≤ 55 mm
135 mm ≥ F > 55 mm
F > 135 mm
The maximum and minimum values for EV vary with ISO sensitivity; the above graph as-
sumes an ISO sensitivity of ISO 200 equivalent. When matrix metering is used, values over
16 / EV are reduced to 16 / EV.
