The Mitakon Zhongyi SpeedMaster 85mm f/1.2 for Sony E is a fully manual, fast-aperture prime lens designed for Sony E-mount cameras and camcorders. Key features include:
Excellent for portraiture and low-light shooting
Great subject/background isolation
High-quality optics for sharp images
Manual aperture and focus for precision adjustments
Full-Frame E-mount. The Mitakon 85mm f/1.2 produces a large enough image circle to cover the full-frame sensors of the a7 III, a7R III, and a7S II. Since it’s an E-mount lens, it’s also fully compatible with APS-C E-mount cameras like the a6400 and a6500.
Short Tele Prime. The 85mm focal length offers a normal field of view that’s great for portraiture and general use.
Fast Aperture. The ultra-fast f/1.2 aperture provides flexibility to shoot in even the lowest of light. It also enables paper-thin depth of field for extreme subject/background isolation.
High-Quality Optics. The six-group/nine-element optical formula features two extra-low dispersion elements and four high-refractive elements to minimize chromatic aberrations and distortion.
High-Quality Build. The metal construction gives this lens a solid feel. Its ultra-smooth manual focus ring works great for both still and video use, while its smooth, stepless aperture ring is ideal for video shooters.
Fully Manual. This lens provides no electronic communication with the camera. You must make all aperture and focus adjustments manually on the lens itself. The aperture you select won’t be displayed on the camera, and it won’t show up in the EXIF data.
