UPDATE: 9/26/2015: It's been 6 months since I've fitted it to my camera and it's worked great for me with no issues or problems. I can't think of any reason why this won't work until I decide to keep this camera. They worked PERFECTLY to connect the twist loop on my vintage strap to my new camera without resorting to the usual nylon straps. Used on modern camera straps. It didn't fit the camera mount for my purpose (and even if it did, I'm not sure I need metal-to-metal contact). I used this item on my OP/TECH USA System Connector Adapt camera. I love that it comes in both black and silver because the black suits my usage. The lock was a bit difficult to open to fit, but I consider it an extra security because it won't open if I don't want it to. If I was going to change it frequently and need to open and close it regularly, I'd look elsewhere. Not only would it hurt too much, I would be worried about how long the lock would last since this part is plastic.
