I have always used various shoulder straps, and like the Op tech straps, but have wondered about the pros and cons of a true shoulder strap, such as the Up Strap. I worry about a shoulder strap slipping off as I bend over, turn around quickly while tracking birds, etc. (with second body hanging on shoulder starp)
Randy,
I agree that the Upstrap is a good product and worth a try. I once tried putting my camera over my shoulder while I was wearing a leather jacket, and it stayed in place! They're not cheap, though....
