Notes on performing multiple flash (common to both wireless

and wired operation)

•To avoid accidental firing, turn off the camera and all flash units before mounting the

master flash unit on or connecting it to the camera.

• The SB-600’s, SB-800’s and SB-80DX’s standby functions are canceled while the

SB-50DX’s standby duration is prolonged to approx. one hour when they are set to

wireless remote flash mode.

• Set the angle of coverage of the remote flash units wider than the picture angle, so that

the subject will receive sufficient illumination even when the angle of the flash head is off

axis from the subject. (In Advanced Wireless Lighting, the zoom-head position is

automatically set to 24 mm, except when the wide-flash adapter is attached.)

Remember, the closer the subject, the wider the angle of coverage required.

• The brightness of the flash illumination is inversely proportional to the square of the

distance between the flash unit and the subject. For example, if the distance between

Speedlight A and the subject is 1 m (3.3 ft.), and Speedlight B is 2 m (6.6 ft.), the

combined brightness of the two Speedlights will be:

A : B = 1

: 2

= 1 : 4 (in meters) or 3.3

: 6.6

= approx. 11 : 44 (in feet)

Therefore, the illumination provided by Speedlight A is four times (or two steps) brighter

than that provided by Speedlight B.

•To ensure good results, it’s recommended to make test shots before shooting

important events.

• Be sure to read the instruction manuals of your camera and Speedlight(s) before use.
