Yongnuo YN17MM F1.7M 17mm
A bright f/1.7 aperture and 17mm wide-angle field of view are packed into a mere 180g body, using 2 aspherical and 2 ED elements with nano multi-layer coating to suppress aberrations. The lens features a weather-sealed metal mount, full-time manual focus override, and an included lens hood for durable, precise control. It suits Micro Four Thirds travel and landscape shooters who need a lightweight, weather-resistant prime for unpredictable conditions.
