Mixing a normal field of view with an exceptionally fast maximum aperture, the black 50mm f/1.1 from 7artisans Photoelectric is a versatile prime designed for M-mount rangefinder cameras. Distinguished by its bright f/1.1 design, this lens excels in low-light conditions and also affords extensive control over depth of field for isolating subjects and using selective focus techniques. A rounded 12-blade diaphragm also contributes to shallow depth of field work by producing a smooth, rounded bokeh quality.

The lens features a Sonnar-type optical design with 7 elements in 6 groups, and individual elements feature a multi-layer coating to help reduce reflections and ghosting for greater contrast and color accuracy. Additionally, the lens has an all-manual design, and focusing operation is benefitted by engraved depth of field and focusing scales.
