I'll never use a "quick release" strap ever again. My used Mamiya 7 came with a fancy strap that had a neoprene & gel pad, and quick release clips. I was immediately suspicious of the clips, but I figured "hey, it's a pro strap, these must be secure."
I took the camera to Beijing a few days later, and the strap seemed to work fine. Then, one day, I was getting into a cab and one of the clips got bumped. I watched as my 7 fell about three feet, smashing down onto a dusty Beijing street. It actually tumbled a few times before landing on the lens.
I picked the camera up, and inspected it. It had a few nicks -- on the film advance, a little chunk out of the lens cap, some scratches on the bottom, and a nick on the lens. However, the film door stayed closed, the rangefinder was still dead-on, and when I turned it on, it worked fine. I kept right on shooting with it in Beijing. All the whining online about the build quality of the 7 is utter hogwash. This is one tough camera.
Of course, I would rather not have discovered that the hard way, so "quick release" straps have earned an unconditional lifetime ban. That Beijing street could easily have been the bottom of the Grand Canyon. 😉
