12mm · f/1.4
The Panasonic Lumix G Leica DG Summilux 12mm F1.4 ASPH is a fast, ultra-sharp wide-angle prime for Micro Four Thirds, praised for its excellent optics at f/1.4 and pleasant bokeh. Its build is solid, all-metal, and weather-sealed, with a smooth aperture ring. Weaknesses include high price ($1,300), no significant advantage stopped down, and limited close-up magnification. It suits photographers needing a fast wide-angle for low-light or shallow depth of field, but is less ideal for landscapes or budget-conscious users.
