When you know you cannot miss that shot for all the money in the world, you just pop out the cap of your lens and go shooting. You spend some hours trying to get more of it and some after-shots that could make touch ups a lot more convenient. And then when you go to pack up and leave you realized you dropped the lens cover somewhere you cannot find it. For such, is the Lens Cap Strap. It isn't an extra accessory to carry but fits on to the main camera strap and fastens your lens cap.

At $18, the Lens Cap Strap does a fine job. It saves you the trouble of buying a new cap or finding it, as well as the agony of seeing your lens unprotected for a few days till you get one.
