For those occasions when you're carrying more than one lens, the Nikon F 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.
