Introducing the Peak Design Lens Kit. Changing lenses is one of the most common workflows in photography. It’s also one of the most frustrating. The Peak Design Lens Kit is an adapter for the Peak Design Capture Kit that lets you change lenses rapidly, with just one hand, and holds your unused lens rigidly and securely. Now you can carry up to 2 lenses on any backpack strap, belt or bag, keeping your spare lens quickly accessible and freeing up the inside of your bag for other gear. Includes 1 Lens Kit adapter. Available for Canon EF, Nikon F or Sony E/FE mounts.
