This flash was designed for use with film cameras and is compatible with N50, N70, N90, N90S, F4, F5 and others in TTL mode. It will work with any Nikon SLR or other with a shoe mount, including digital. To work with a digital camera, the TTL does not work. It works with the exposure sensor built-in on the flash. You select a range and set the f stop to the recommended setting and shoot.
The illuminated LCD panel displays TTL, manual or fill flash modes, second curtain synchronization for Canon and Nikon versions and flash confirmation. The guide number range from 80 to 132 assures ample power from either 4 AA batteries or, with the optional, Sunpak TR-Pak IIa Power Pack. To conserve battery power, the PZ4000AF features a sleep mode. If not fired after a few minutes, the PZ4000AF goes into a standby mode. Reactivating the flash requires only a slight touch to the shutter release button of the camera to bring the flash back into a readiness mode.
