A battery magazine system allows fast battery replacement. The battery magazine can be inserted in any orientation, minimising fumbling and lost time. Eight AA batteries are stored (it can be used with four AA batteries). The External Battery Adaptor for Flash (FA-EBA1) takes priority so that minimal demand is placed on the internal HVL-F60RM batteries.
To meet professional use, reliability is enhanced. For example, cable stress relief has been carefully designed for maximum durability (see illustration). Seals around enclosure joints and a rubber magazine lid gasket minimise the possibility of dust or moisture intrusion.
660 continuous flashes can be produced with fully charged batteries, providing the endurance needed for demanding professional applications.
