Guide Number ( GN ) Guide numbers indicate flash light intensity. From the guide number, you can easily obtain the proper aperture setting required for an optimum exposure. Aperture [f-number] = GN/flash-to-subject distance [m] Example : GN33/3m = f11 · With autofocus cameras (except the SF series) attached with an FA J, FA or A lens and the 645N, 645NII cameras, a bar graph displayed on the LCD panel will indicate the approximate flash range.

Notes on Wireless Flash Control (P-TTL photography) With contrast-control-sync flash · If the camera's built-in flash is not used, leading-curtain sync photography will result even when the sync mode switch is set to contrast-control-sync with one flash unit. · With contrast-control-sync flash and the *ist, MZ-S, MZ-L/MZ-6/ZX-L cameras, the flash mode is set automatically to P-TTL. With other autofocus cameras, or 67II camera, TTL auto flash is set automatically. · Instead of the camera's built-in flash, you can also use a flash unit having contrast-controlsync flash function. With a single flash With the autofocus cameras and 67II cameras which do not have a built-in flash, you can use two or more flash units (AF080C, AF500FTZ, or AF330FTZ) to set the contrast-control-sync flash mode.
