Zhong Yi Optics announced the Mitakon Speedmaster90mm f/1.5 manual-focus portrait lens for full frame Leica M, Canon RF and Sony FE mounts.
According to Zhong Yi Optics, the new portrait prime has a medium telephoto angle, great depth of field control, and can render distortion-free portraits using well-controlled color artifacts. Zhong Yi Optics claims that the Leica M-mount version can autofocus using third-party adapters, such as those from Megadap or Techart. These adapters enable Nikon Z and Sony users, as well as Sony users, to benefit from the Leica M mounting’s short flange distance and achieve autofocus with the 90mm F/1.5 lens that supports face detection and works in conjunction with the camera’s in-body image stabilization.
The lens is composed of nine elements, divided into six groups. Two of these elements are extra-low dipersion elements, and two are high refraction, low dispersion elements. This formula is said to produce outstanding image quality, with minimal color fringing or chromatic aberration. Zhong Yi claims that the lens’ color rendition is “vividly similar” to what the eye sees.
According to the lens’ apochromatic classification (APO), bright to dark transitions and highlights in photos are reproduced nearly completely without color artifacting. Zhong Yi claims that axial chromatic aberrations can be corrected using elements of special glass with anomalous part dispersion.
The 90mm f/1.5 is described as capable of creating an “ethereal” atmosphere in images due to its blurry bokeh at maximum aperture. This is due to a combination of its optics, focal length and nine-bladed round iris design.
Zhong Yi claims that the 90mm lens is very good in low-light situations due to its super-fast wide-open aperture of f/1.5. It can reproduce light sources evenly across the entire frame, while suppressing coma flare, according to Zhong Yi.
Here are some sample images taken with the lens, provided by Zhong Yi Optics.
Zhong Yi Optics sells the Mitakon Speedmaster90mm f/1.5 directly for $599 for Canon RF and Nikon Z mounts, $649 for Leica M and $649 respectively.
