The HVL-F56M provides remarkable flash output with the maximum guide number of 56m (184 feet) at ISO100 in a compact body. Flash coverage is available from 24mm to 85mm focal lengths, and further extends to the 17mm focal length with a built-in wide-angle adapter. It assures highly reliable metering accuracy with ADI (Advanced Distance Integration) flash metering in combination with Sony's lenses with distance encoder and the Sony Alpha 100 DSLR (or the older Minolta Dynax 7D or 5D cameras). It also supports versatile remote flash photography with Wireless/Remote High-speed Sync when used as an off-camera flash. The AF illuminator covers the Alpha100's 9-point sensors in the wide focus area. Furthermore, the flash head tilts 10° downward for close-up photography. Also compatible with the Konica Minolta Dynax 7D, 5D, Dimage 7 and the Dimage 5.
