This is an Hirose style connector with 5 alignment keys, but the original manufacturer or application is unknown.   The Female connector was manufactured by T.M.W.   The Female connector has 30 pins, A through Z (no L or S), and a through f.   It is uncertain whether this connector was originally designated as a 30 pin or 26 pin.    

The other end is a standard 14 pin locking Male camera adapter connector.

We suspect that it may be an Hitachi cable, but that has not been verified.   It is being sold strictly as is.
