The PZ 4000AF brings Sunpak's reputation for quality, performance and value to auto zoom flashes. Each version features a motorized zoom head that automatically adjusts the flash to match the focal lengths of lenses from 28mm to 80mm in four distinct settings. If preferred, the zoom head can be manually controlled at the press of a button. For creative bounce lighting control, the head can be adjusted to 90 degrees. Nikon system. Guide No. 130.
