Xpix XPIX-PX-CF1-NM Digital Slave Flash for Digital; SLR & DSLR Mirrorless for Canon Nikon Camera; Black (Discontinued)

The Xpix Digital Slave Flash is a Flash with selectable firing. it has a switch on the back which allows you to select between the two different triggering modes, making it compatible with any camera on the market. Ordinary slave units do not work with many digital cameras because these cameras use a very rapid set of pre-flashes to set the white balance of the camera's image sensor chip but not the exposure. The slaves will typically fire on the pre-flash it senses, while the digital camera captures the image on the last flash. Thus, the extra light from the slave does not show up in the digital camera photo. The flash units are designed to fire on a flash, sensed by their built-in optical sensor and circuitry, so the effect of the flash is not lost. It runs on two AA batteries
