A truly fast short telephoto prime designed for Pentax K mount cameras, the Speedmaster 85mm f/1.2 Lens from Mitakon Zhongyi pairs the bright maximum aperture with a portrait-length perspective for extensive focus control and enhanced low-light shooting. The optical design incorporates two extra-low dispersion elements with four high refractive index elements to reduce chromatic aberrations and distortions in order to achieve notable sharpness, even at wide apertures. Additionally, the lens features a manual focus design with a floating elements system, along with a de-clicked, silent aperture ring to benefit both still and video applications. Ideally suited for portraiture applications, the refined optical design, fast maximum aperture, and longer-than-normal perspective help to isolate subject matter and deliver a high degree of sharpness and clarity.

Mitakon Zhongyi Speedmaster 85mm f/1.2 Overview
Portrait-length 85mm prime is compatible with full-frame Pentax K mount cameras, and can also be used with APS-C-sized sensors where it will provide a 127.5mm equivalent focal length.
Fast f/1.2 maximum aperture benefits working in difficult lighting conditions and also enables extensive control over your focus position to benefit the use of selective focus and shallow depth of field techniques.
Two extra-low dispersion elements and four high refractive index elements help to reduce chromatic aberrations and distortions throughout the aperture range for greater sharpness, clarity, and color accuracy.
Manual focus design utilizes a floating elements system to permit focusing on subjects as close as 3.3' away.
De-clicked, stepless aperture ring permits smooth, silent aperture adjustment to benefit video applications.
An 11-blade rounded diaphragm contributes a pleasing out-of-focus quality when working with selective focus techniques.
All-metal lens barrel features printed depth of field and focus scales. Additionally, a metal lens mount also offers increased durability between the lens and camera.

Mitakon Zhongyi Speedmaster 85mm f/1.2 Reviews
This lens is quite amazing

This lens build like a tank and is quite heavy. That might be appealing to certain videographer. The focus ring is so smooth. It has too much resistance to turn when I first use it. After time it get loose and become perfect to turn by hand. The image at f1.2 is quite good. It does has low contrast and prone to flare at f1.2 but the center resolution is very good. Stop a bit to f1.4-1.6 increase contrast and reduce flare. I do not see other options for ef mount that has manual aperture ring and has great image quality even at f1.2. Do not overlook this lens if you are looking for a fast 85mm full frame lens that can be adapt to any system.
Best 85mm ever.

This lens is the best prime I've owned. The lens is solid metal and glass. The lens is exceptionally sharp, and colors are reproduced perfectly. if you like Zeiss lenses, you'll like this one because this is better in my opinion. It is a declicked aperture that turns very smoothly. I use this lens with my Nikon F6 on aperture priority mode.

question
If I use this on an A7Rii and use Metabones Adapter Ultra ii 0.71x, is it still going to be fullframe? Do I need to crop it?
The lens and camera are both full-frame, but the Metabones 0.71x adapter does make the lens perform 29% wider than normal, so it would actually be a 60mm equivalent.

Does this focus the Canon/Zeiss direction or the Pentax/Nikon direction? Photos show it focusing and f-stopping backwards to all my other Nikon lenses.
The focus ring on the Mitakon Zhongyi Speedmaster 85mm f/1.2 Lens for Nikon F focuses counter clockwise or in other words, normal like Canon and all other camera brands.
