Nikon NIKONOS-V Instruction Manual page 51

The Nikonos-V, which has only an X-contact, synchro-
nizes with speedlights when the shutter speed set is
1/90sec. or slower. (Shutter speed sync ranges are
shown in the following chart.)
o
When connecting a special electronic flash unit with a provi-
sion for time lag, set the shutter speed at 1/60sec. or slower
depending upon the time lag.
o
Connecting other manufacturers' flash units may damage
the Nikonos-V's IC circuitry. Also, units with a high-voltage
sync circuit may adversely affect shutter speed precision.
