Compatible with select <b>FUJIFILM</b> X-Series cameras, the <b>EF-X8 Flash</b> is a sleek and portable shoe-mounted flash featuring a guide number of 26.2' at ISO 100. It is compatible with FUJIFILM's TTL system for automatic exposure control, and also supports manual power control from 1/1 to 1/64 power with output adjustment handled through the camera's menu system. It can also function as a commander for triggering remote-synced flashes and it supports slow sync TTL settings for creative versatility. To maintain its compact design, the flash is powered entirely by the camera's body.
