The Bolt DSMC2 is a RED camera module with a built-in Bolt TX that mounts seamlessly to the back of DSMC2 cameras, getting both pass-through power and video via the camera's pogo pin connectors. Basically, it saves the trouble of having to mount a Bolt TX, keeping your rig clean of extra cables and mounting accessories.
Bas Goossens, DP and founder of the Ministry of Frames in The Netherlands, recently took the Bolt 500 DSMC2 on a shoot with Cirque du Soleil. Check out his in-depth review here.
