Yeah, yeah, yeah. The challenge and exhibition is meant for shoes you wear on your feet, but hey as a flash guy, hot-shoe to me has a different meaning. This picture was taken to show the locking pin of Olympus flashes. A question came up in another forum about off-camera cables, and I mentioned that the Promaster cable did not have a hole for the locking pin, and this picture was to show what the locking pin is. From right to left on the top: Promaster Olympus module, FL-50 flash, FL-36 flash with a FL-CB05 on the bottom.
