Fast and wide, the 21mm f/1.5 from TTArtisan is an ultra-wide prime designed for Leica M-mount rangefinder cameras. The broad field of view is complemented by the bright f/1.5 maximum aperture, which excels in low-light conditions as well as for isolating subjects using selective focus techniques. The lens's manual focus design permits working with subjects as close as 2.3' away and it features a 10-blade diaphragm that contributes to a smooth bokeh quality. Additionally, a lens hood is included that protects the front of the lens as well as reduces stray light from causing flare.
