Manufacturer description
Zhong Yi Optics proudly presents our ten-times cheaper 90mm f/1.5 portrait lens today. 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 in Leica M mounts can also realise autofocus with third-party adapters. It is available in FE, RF, Z and M mount.
Mitakon Speedmaster 90mm f/1.5 renders a dreamlike ambiance for the images produced. Its buttery bokeh at maximum aperture blurs with the background perfectly. Combining fast aperture and long focal length in one lens, the shallow depth of field enables a flawless separation of the main subject and background. 9-bladed round iris enables the round-shape bokeh that all photographers would have ever wished.
For low light environment, our wide aperture is the best match for your shooting. Mitakon Speedmaster 90mm f/1.5 can replicate light source consistently over the entire frame, without the presence of coma flare. The f/1.5 fast aperture also allows photographers to capture charming moments at night with ease. The Mitakon Speedmaster is an excellent lens for night photography.
9 elements in 6 groups optics formula of the prime lens bring outstanding image quality. Sharply defined details and contrast can still be retained at a wide-open aperture. Two extra-low dispersion elements reduce color fringing and chromatic aberrations. The color rendering is also vividly close to the human eye’s capture.
Bright-dark transitions in the image, and especially highlights, are reproduced almost completely free of color artifacts with our Speedmaster 90mm f/1.5. Chromatic aberrations (axial chromatic aberrations) are corrected with elements of special glass with anomalous partial dispersion. The chromatic aberrations are therefore too minimal to observe.
A modern 90mm lens is sometimes referred as a “standard lens for architecture.” The approximate 27° view angle is also a best perspective of portraits. It allows an exquisite image to the subject while avoiding the compression effects offered by a longer focal length lens.
