Yongnuo YN24-EX Lock ring

One of the annoying things about the Yongnuo YN24-EX twin flash is when you are trying to photograph anything, the flash heads keep twisting around the mount adapter rings. In the past I jammed bits of paper in place to stop this, but those were not the ideal solution. Instead I have designed these locking rings for each of the four sizes od adapter, 52mm, 58mm, 67mm and 72mm. Just fit them to each adapter ring and the lock in place on the outside of the thread. When you screw the adapter onto your lens, tighten the adapter ring up with the rounded cut-out on the printed part at the top. When you fit the head assembly the four square cut-outs lock the flash mount in place stopping all that annoying floppyness that scares off your subjects.
