I should mention the reason I went with that in the first place is, well factory camera straps suck. No news there.
But when I was working and going from landscape to portrait the strap kept falling in the way of something, lens, my eye, flash, something.
One day when I was about to throw the camera across the studio because of strap interference again, I thought , what I need is a a single point attachment of some kind and this crap will stop.
Hummmm single point, I got something like that.
Worked well ,real well, but I found out the hard way about having the ring too small when the d800 and the 70-200 went to the ground after the small ring twist pulled out of the sling hook.
I would like to find a small hook or bolt or fastener to replace the ring, but nothing I have tried has worked as well.
