The Lowepro S&F Lens Exchange Case 200AW (Black) is designed to carry up to a 70-200mm lens f/2.8 lens. The case is made with a lens exchange design that allows user to take out the lens with one hand. It increases ease of operation and lens exchange speed. The dual-compartment design temporarily holds 2 lenses for that lens-changing moment; collapses back to a single-lens shape once lenses are exchanged. There are 2 mesh side pockets that have easy-to-reach storage space for lens cap, body cap, filter, etc. It has a built-in All-Weather AW Cover that protects the case from the elements.
