Built with an aluminum chassis and an enhanced lens coating, this 50mm 1.8S lens includes rear sealing to prevent water and dust ingress. The design also effectively improves signal conductivity and resistance for reliable electronic performance. A simple dustproof layout and a dual-function button with sensible placement enable quick, intuitive operation and easy switching.
