The Lowepro S&F Lens Exchange 100 AW Case will help to improve workflow, increase speed and allow for the safe swap out of lenses. The breakthrough design lets you change out a lens with one hand. The patent-pending lens-exchange feature temporarily holds and separates the two lenses as you detach the working lens and grab the second. The wide-grip zipper handle allows quick and easy access to main compartment. The SlipLock attachment tab allows the case to be worn on user's belt or S&F Series belt or other compatible products.
