Oh celebrities, they can be so squirrelly sometimes when it comes to the snooping and intrusive paparazzi. That’s why you gotta have your DSLR available at a moments notice. The SpiderPro system incorporates a quick release system that attaches to any belt or their optional Spider Belt for heavier loads, using the camera’s built-in hardware. The Spider Pin and Plate attaches the tripod mount on the bottom of the camera and slips in and out of the clipping system, which can be locked for occasional access or unlocked for unfettered access. Since it’s a bit difficult to explain I recommend watching their video.
You can nab the complete system for $110.
