Now in its third version, the Canon RF-mount Speedmaster 50mm f/0.95 III from Mitakon-Zhongyi is an exceptionally fast normal-length prime with enhanced flare resistance. Obviously distinguished by its f/0.95 maximum aperture, this lens excels in low-light situations and affords impressive control over depth of field. Its optical design incorporates one high refractive index element along with five ultra-low dispersion elements to produce well-corrected imagery void of spherical and chromatic aberrations. The lens's manual focus design permits working with subjects as close as 1.6' away and an 11-blade diaphragm contributes to a pleasing bokeh quality.
