As Dennis said, it all depends on the size of the ring. The size of the rings that came with the Domke are just about perfect, they fit with just a touch of movement but not much so the ring cannot touch anything except the inside of the strap faster. No danger of scratching the hood or anything else (at least on my 3.5T).

I'll measure the ring and post that with a picture, hopefully tomorrow.
