Ever since I switched to a Black Rapid strap I have been a little paranoid about keeping the thread tightened to the camera or lens. This morning I switched from a wide angle lens in my bag to the 100-400 and made sure the strap was nicely tightened to the lens foot and off I walked.
Just as I was walking over a concrete section of reservoir bank right next to the water the camera body dropped off the lens and bounced on the concrete. Fortunately I managed to stop it before it fell another 10 feet onto more concrete and then into the water. It has a few scratches and a small piece of metal chipped off by the battery compartment but apart form that all seems to be working fine.
I have checked focus etc but is there anything else I should test? Last thing I want to do is miss a load of opportunities because of a bit of damage.
Also thinking of putting a second Black Rapid FastenR on the camera then joining it with some cord to the one on the foot. That should cover most eventualities and not cause any problems other than speed of changing setup. It is not the cost of damaging kit that worries me, just the amout of time without awaiting repair.
