This professional-quality lens is designed for Lumix Micro Four Thirds cameras like the GH5(S) and G9, catering to both photographers and videographers. It features a constant f/1.7 aperture, a clickless aperture ring ideal for videography, and a focus clutch mechanism. As the world's first standard zoom lens with an f1.7 aperture across its entire range, it delivers beautiful bokeh and impressive image quality across the 20-50mm (35mm equivalent) zoom range. Constructed with 17 elements in 12 groups, including 3 aspherical lenses and 4 ED extra-low dispersion lenses, it effectively suppresses chromatic aberrations and distortion for superb high resolution. The lens is built to stringent Leica specifications.
