Nikon SB-800 instruction manual Multiple flash shooting using cords, Speedlight Coefficient

Multiple flash shooting using cords

The SB-800 can be used with Speedlights compatible with the TTL auto flash mode to perform multiple flash shooting using cords.

•Use of the SB-50DX and SB-23 as remote flash units is not recommended, because the standby function cannot be canceled.

•Speedlights SB-11, SB-14, SB-140, and SB-21B cannot be used with the F-401/N4004 or F-401s/N4004s as either master or remote flash units.

•There is no limitation in usable cameras.

•With cameras compatible with CLS and digital SLRs not compatible with CLS, Manual flash operation only is possible.

■■■ The maximum number of flash units to be connected using cords

•Up to five units including the master flash unit can be used for multiple flash photography at a total cable length of 10m (33 ft.).

•Make sure the combined total of the coefficients in the table below for all flash units used together does not exceed 20 at 20°C (68°F) or 13 at 40°C (104°F).

•If it exceeds these figures, you may not be able to take a second shot after the first one. In this case, turn off the power of all flash units and reduce the total number of flash units connected.
