The B.E.C. BECFS4 is a mounting box specifically designed to hold the Focus Enhancements FireStore FS-4 digital recorder. The bracket allows users to conveniently mount their FireStore to their camera. The box mounts on all cameras with the Sony screw configuration, most commonly found on the NP/1 holder, the IDX NP/1 system and Anton Bauer Gold Mount system.
This mounting box will not hold an extended battery; it is specifically designed to be used with a standard sized FireStore battery.
