In cases where you are carrying more than one lens, the Nikon F Lens Changing Kit v2 from Peak Design will help you change lenses faster and with more flexibility.

Simply attach the lens changing kit to a backpack, strap, bag, or belt. With this kit, you can change lenses with one hand and have a convenient place to store the lens you just removed. By storing the lens outside of your camera bag, you'll free up space for other equipment.
