Zhong Yi introduces another portrait focal length -- the new Mitakon Speedmaster 90mm f/1.5 lens for full-frame mirrorless cameras offers a 27° angle of view and an apochromatic optical design consisting of 9 elements in 6 groups, including two ED elements. Chromatic aberration is said to be minimal.

The aperture consists of 9 blades, and the minimum focusing distance is 110cm. The manual optics will be available for Sony FE, Canon RF, Nikon Z and Leica M -- some adapters are available for Nikon and Sony users, allowing to use various autofocus modes of their camera with the Leica M variant. With the Megadap MTZ11 or the Techart TZM-01/LM-EA7 adapter, Zhong Yi says AF-S, AF-C, AF-F, and eye/face detection modes with IBIS should work.
The Mitakon Speedmaster 90mm f/1.5 weighs 770g with dimensions of 74mm (diameter) x 102mm (length), and the filter size is 67mm. The price is or for the Leica variant. Speaking of which, this new optic is pretty clearly "modeled" after the Leica SUMMILUX-M 90mm lens f/1.5 ASPH, a lens quite at the other end of the price scale -- it costs about 12,000 euros.
