Immediately when purchasing it, most everyone considers protecting their camera for travel and home. Typically, everyone purchases a camera case or bag to haul it around. Some travelers purchase a camera strap with a steel cable in it to prevent slash and grab thefts.
The same travelers rarely think about protecting their SLR or DSLR lenses from being damaged, which when you think about it, makes little sense.
SLR and DSLR users generally own at least two lenses for their camera, and often have more. Looking at many vacationers' stable of lenses, I often see a wide angle zoom, a normal-telephoto zoom, and often a fast prime lens. Sometimes they also own a macro or telephoto lens.
If you add up the cost of the lenses, even when they own just two, they will equal or more likely exceed the value of their camera.
I was in Paris a few years ago. I went to the Eiffel Tower one evening to take night photos. The crowd at the tower was huge. After finishing we walked back to the Metro to return to our hotel along with many who had visited the Tower that evening. The neighborhood is filled with row homes having front steps with metal railings.
Along the way I was accidental pushed into one of those railings by the crowd. The front of my lens hit the railing. Despite the lens cap on the lens, the UV filter atop the lens was smashed.
