THIS IS DANGEROUS AND MIGHT DAMAGE YOUR CAMERA. NO WARRANTIES. NO GUARANTEES. DO NOT TAUNT. IF IT BREAKS, YOU GET TO KEEP BOTH PIECES.
Be careful using this for production work: Please test your camera and the firmware extensively before committing to using it on a set or any "one-take only" events. It has proven fairly stable in use, but there are still some rough edges.
Please review the FAQ. You have questions. It has answers.
