Exposure Program
The following graph shows the exposure program for mode P (ISO 100, maximum lens aperture f/1.4):
| 1 |
F (lens focal length) ≤ 55 mm |
|---|---|
| 2 |
55 mm < F ≤ 135 mm |
| 3 |
135 mm < F |
| 4 |
Metering range: −3 to 20 EV |
|---|---|
| 5 |
Aperture |
| 6 |
Seconds (shutter speed) |
-
The maximum and minimum values for EV vary with the metering range.
-
When matrix metering is used, values over 17 1/3 EV are reduced to 17 1/3 EV.
