For those occasions when you're carrying more than one lens, the Canon EF CaptureLENS from Peak Design will help you change lenses faster, and with added versatility. Simply attach the included clip and lens kit adapter to a backpack, strap, bag, or belt. With the CaptureLENS you can change lenses with one hand, while at the same time, have a convenient place to store the lens you just removed. An added benefit is that by storing the lens outside of your camera bag; space will be freed up for other gear.
