The Fuji EF-20 Flashgun combines a compact design and efficient controls and is the ideal for carrying in a pocket or bag and providing any additional lighting. The hotshoe folds cleverly into the flash body to minimise space and simply rotates out when required for use. With the guide number 20 (ISO 100-m) and operating TTL with the FinePix X100 and HS20EXR cameras, the EF-20 provides superb lighting for each shot. The in-built wide panel diffuser provides effective flash distribution while EV adjustment can be made up +/-1.0EV in 5 steps (-1, -0.5, 0, +0.5, +1). Powered by 2 AA batteries, the quick charge time of approx. 4 seconds keeps the EF-20 ready for use.
