The SIGMA 50mm F1.2 DG DN Art for Leica L Mount features a bright F1.2 aperture with a 13 rounded diaphragm blades that produces beautiful bokeh effects. Utilises the latest optical design, the lens produces sharp images across the whole frame with exceptional contrast and colour. Focus breathing is also heavily suppressed allowing videographers to capture creative shots with ease. Impressive optical quality through the entire focusing range. Achieved by correcting spherical aberration, sagittal coma flare, axial chromatic aberration, and other aberrations such as double-line bokeh, the lens produces a natural bokeh with a smooth blur and without colour bleeding from the focal plane. The lens also implements a floating focus system that improves its short-range performance. This ensures a high-level of optical quality throughout the entire focusing range. SIGMA’s first ever 13 diaphragm blade diaphragm.
