I use a Nikon DSLR most of the time when I am shooting photos. The thing I always seem to misplace is the lens cap. I have had it fall out of my pocket several times while moving around taking photos and my wife always lays it somewhere when she uses the camera and can't find it later. I have spent much more time than I ever wanted to searching for my lens cap. A cool new product has landed on Kickstarter that will prevent lost lens caps if it gets the needed funds.
