The Camplex BLACKJACK is a camera-back adapter and Neutrik opticalCON DUO converter for Blackmagic's ATEM fiber camera converter, sold separately. It connects into the ATEM's LC connection and converts it to an opticalCON DUO interface to provide a substantially more ruggedized, durable connection. An optional tactical fiber cable with an opticalCON connector is required.
BLACKJACK sandwiches in the ATEM and attaches it to any camera or rig via one of several optional BLACKJACK adapter plates, which come in cheese plate, V-mount, and Gold-mount versions.
