A truly fast short telephoto prime designed for Sony A mount cameras, the Speedmaster 85mm f/1.2 Lens from Mitakon Zhongyi pairs the bright maximum aperture with a portrait-length perspective for extensive focus control and enhanced low-light shooting. The optical design incorporates two extra-low dispersion elements with four high refractive index elements to reduce chromatic aberrations and distortions in order to achieve notable sharpness, even at wide apertures. Additionally, the lens features a manual focus design with a floating elements system, along with a de-clicked, silent aperture ring to benefit both still and video applications. Ideally suited for portraiture applications, the refined optical design, fast maximum aperture, and longer-than-normal perspective help to isolate subject matter and deliver a high degree of sharpness and clarity.
