Using the Built-in Flash Calculating Aperture Value from Shooting Distance ƈ The following equation calculates the aperture value for shooting distances. Aperture Value Used F = Guide number ÷ Shooting distance When sensitivity is [ISO 200] and shooting distance is 5.2 m, aperture value is: F = 15.6 ÷ 5.2 = 3 If the resulting number (3, in the above example) is not available as a lens aperture, the smaller number that is closest (2.8, in the above example) is generally used. ŝ211Ş

Using the Built-in Flash
The following equation calculates the aperture value for shooting distances.
Aperture Value Used F = Guide number ÷ Shooting distance
When sensitivity is [ISO 200] and shooting distance is 5.2 m, aperture value is:
F = 15.6 ÷ 5.2 = 3
If the resulting number (3, in the above example) is not available as a lens aperture, the smaller
number that is closest (2.8, in the above example) is generally used.
