* The table shows the flash shooting distance range for print films. The flash shooting distance
range of color slide film is approx. 2/3 that of print film with the same ISO film speed rating.
• The maximum flash shooting distance can also be calculated by dividing the
guide number by the aperture value selected.
Example: When f/2.8 is selected with ISO 100 film using the camera's built-in
Speedlight, the maximum flash shooting distance will be;
12/2.8 = approx. 4.2m
