I had looked at much more expensive camera/binocular harness-type systems, and had bought the elasticated version of this strap. I was very pleased with it, but sadly left it in a restaurant. So I went and bought another - the non-elastic one this time. I preferred it with my Canon SLR. The elasticated one tended to 'bounce' a bit - probably OK on a lighter camera - whereasy the simpler rigid version does the job fine as far as I am concerned. Can carry the camera for a few hours with no fatigue.
