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
prime designed for full-frame and 35mm Leica M-mount rangefinder cameras.
