The Leica Noctilux-M 75mm f/1.25 ASPH is an extremely fast lens and wonderful addition to the Leica M-System lens portfolio. It’s perfect for low-light conditions. Along with exceptional imaging performance and unique bokeh, the wafer-thin depth of focus isolates subjects with extreme precision. The focal length of 75mm makes it an ideal choice for portraits. It features two aspherical elements and anomalous partial/low dispersion glass. It has a filter thread size of 67mm and weighs 1055g.
