Optimum shooting distance
Optimum shooting distance
Use the following formula to calculate the optimum shooting distance.
Optimum shooting distance (m)
= 14 × ISO sensitivity coeffi cient (1 for ISO 100) ÷ Aperture value (F)
ISO sensitivity and their coeffi cients
ISO sensitivity 25 50 100 200 400 800 1600 3200
Coeffi cient 0.5 0.71 1.0 1.4 2.0 2.8 4.0 5.6
