Hmmmm I have an Optech with quick release.... so far so good and its more comfortable than nikon strap IMO... but after a month of using i decided not to use a strap with quick release.... it is all psycological. Somehow, I am just worried that my heavy glass would break if the quick release got activated by accident or should the quick release give way. no point putting thousand of dollars at risk so now i use the strap included with my camera... just my $0.02 worth
Optech straps is a American product, we all know what kind of country is this, if anyone is worry of accidentally unclip it, this is extremely paranoid, I dont think it happen it before, if not optech straps will close down long ago.
I always see photographers leave the camera on the table but let the straps dangling at the table edge, this is even higher chance that the camera will hit the ground.
The quick release facilitates removal... It's useful when you're storing the camera into the dry cabinet.. Remove the strap and leave it out to sun.. The strap absorbs lots of moisture so you'd not want to put it into the cabinet with your lenses and cameras.
