¢2 Multiplying these lighting angles (mm) by two yields equivalent values for
35 mm films.
≥ In the [FP MANUAL] mode, the following formula can be used to obtain the guide
numbers (GN) when any setting except 1/1 is used for the light quantity.
Guide number (GN) = Guide number for 1/1 k light quantity ratio
