Sunpak PZ40X Hot-shoe clip-on flash

The Sunpak PZ40X is a powerful, full-featured, lightweight, shoe-mount electronic flash unit for digital and film cameras, that is available in Nikon, Canon, and Minolta TTL dedicated configurations, and will also work manually with cameras having a non-dedicated, single-contact hot shoe. It is 40 percent smaller and significantly lighter than previous flash units with the same features and power output, with an impressive ISO 100 guide number of 102 at the 50mm zoom setting. Advanced features of the Sunpak PZ40X include: TTL auto flash (D-TTL for Nikon, E-TTL for Canon, and ADI for Minolta); large, full-info, backlit LCD for controlling and monitoring all settings, power zoom-bounce flash head covering 35mm focal lengths from 24-80mm, continuously variable or in 5 manual power-ratio steps, with tilt positions from zero to straight up for maximum bounce flexibility, built-in near-IR autofocus aid light that turns on automatically when needed, 5 power settings down to 1/16, flash exposure confirmation and bar graph flash range display, plus power-saving circuitry that automatically turns to Power Saving Standby mode after 5 minutes. The Sunpak PZ40X is powered by two AA alkaline or Ni-MH batteries. An optional Wide-Angle Panel provides flash coverage for lenses down to 17mm.
