Zhong Yi Optics Unveils the Budget-Friendly Mitakon Speedmaster 90mm f/1.5 Lens

Chinese manufacturer Zhong Yi Optics has announced the release of its new Mitakon Speedmaster 90mm f/1.5 lens, a manual focus portrait lens for full-frame Leica M, Canon RF, Sony FE, and Nikon Z mounts. With a medium telephoto angle of view and great control of depth of view, the lens produces perfect distortion-free portraits with well-controlled color artifacts.

The lens is constructed of nine elements in six groups, including two extra-low dispersion elements and two high-refractive elements. It also has a nine-blade aperture diaphragm, a minimum focusing distance of 110cm, a 67mm front filter thread, and an f/1.5 through f/16 aperture range. Zhong Yi Optics also says that the Leica M mount version can autofocus with third-party adapters such as the ones from Techart or Megadap. These adapters allow Nikon Z and Sony users to take advantage of the short flange distance of the Leica M mount and gain autofocus with the 90mm f/1.5 that supports face and eye detection as well as work in tandem with the camera’s in-body image stabilization.

The lens is classified as apochromatic (APO) and as such the company claims that bright to dark transitions in a photo (and especially highlights) are reproduced almost completely free of color artifacts. Axial chromatic aberrations are corrected with elements of special glass with anomalous partial dispersion, and Zhong Yi says the result are chromatic aberrations that are too minimal to see.

It describes the 90mm f/1.5 as capable of creating a dreamlike ambiance in images thanks to its buttery bokeh at maximum aperture thanks to a mixture of its optics, the focal length, and the nine-bladed rounded iris design.

Here some sample pictures:

The Mitakon Speedmaster 90mm f/1.5 is available directly from Zhong Yi Optics for $599 for Canon RF, Nikon Z, and Sony E mounts and $649 for Leica M mount.
