An improvement from the original Leica Dg Summilux lens that became a must-have for any Lumix G series mirrorless Micro Four Thirds photographer due to its clean optical sharpness and the unique soft-focusing background effect it can generate, now with a rugged dust and splash-resistant design. The F1.4 aperture provides for super bright light gathering under difficult low light conditions while the Panasonic Nano Surface Coating nearly eliminates common ghosting and flaring that can accompany wide open aperture photography. Supporting versatile use with its 50mm (35mm camera equivalent) focal length, the Leica Dg Summilux 25mm / F1.4 Ii Asph. features stunningly high resolution and a descriptive performance from the center to the corners of the image despite its large aperture. It provides a smooth defocus for a beautiful bokeh effect that makes pictures even more impressive.
