Panasonic has just announced the Leica DG Summilux 25mm f/1.4 ASPH, a fast standard lens for the Micro Four Thirds system. Comprising 9 elements arranged in 7 groups (including 2 aspherical elements and 1 ultra-high-refractive-index lens element), the Leica DG Summilux 25mm f1.4 ASPH features Nano Surface Coating to minimise ghosting and flare, and an iris diaphragm with seven rounded aperture blades for pleasing bokeh. The lens weighs in at approximately 200 grams and takes small, 46mm filters. With its maximum aperture of f/1.4, the Leica DG Summilux 25mm f1.4 ASPH is currently the fastest auto-focus lens with a native Micro Four Thirds mount.
