LEICA DG SUMMILUX 12mm/F1.4 ASPH. lens unit integrates two aspherical lenses, two UED lenses and an ED lens. These five special lenses make it possible to clear the stringent LEICA standards for exceptional image quality. High resolution is achieved from the centre of the image to the corners by suppressing sagittal flare. Users can take advantage of this lens to shoot starry skies or night scenes containing illumination, capturing true-to-life images with minimal blurring and distortion all the way to the edges.
LEICA DG SUMMILUX 12mm/F1.4 ASPH. enables photographers to capture dynamic landscapes with rich perspective across a wide angle. It also allows indoor shooting in low lighting and produces an impressive, natural defocusing effect with its F1.4 large aperture.
