Nikon SB-E Flash

Introduced with the Nikon EM camera in 1979 as a companion dedicated flash unit which means it is primarily intended for use with certain models and has special features when so used. It is an automatic light-sensing energy-saving flash with no manual or non-auto setting.

With the EM or Nikon FE or other equivalent Nikon camera models set to AUTO, the flash will automatically set the correct flash sync speed to the maximum sync speed, in the case of EM and FE, it is 1/90 second, and controls an LED in the viewfinder which serves as a ready-light or a warning light either to help you select correct aperture or to warn you of possible improper procedures.
