The product was designed to express the robustness and functional beauty of a professional instrument that controls the high optical performance of Fujifilm’s lenses when focusing or zooming. The precisely assembled components are made of different materials, including the exterior body of machined aluminum with alumite treatment, the rubber-coated grip that fits well into the user’s hand and prevents slipping, and the rubber cap to keep raindrops from getting inside the product. The black, solid impression of the overall design is suitable for an optical device that becomes the choice of professionals.
