Nikon’s upcoming mirrorless camera is rumored to have two electric AF motors

The next Nikon mirrorless camera/lenses are rumored to have TWO electric AF motors - each driving a separate group of lens elements for faster and more precise autofocusing. I am still not sure about the details, but I was told that this is a new "internal focusing" technology, where TWO groups of lens elements will be moved independently from each other.

요약

다가오고있는니콘미러리스바디와렌즈가 2 개의 electric AF모터를갖는다는소문이있다. 더빠르고정확한오토포커싱을위해 2 개의각각의모터가 서로다른렌즈그룹(렌즈군)을 독립적으로움직일수있다고하며 나는디테일한것은모르겠으나 새로운 "인터널포커싱"기술이라고들었다.

음..구라가아니라면 니콘이더욱강력한AF모터에 Z마운트까지갖는걸까요..ㅎㄷㄷ 레트로필카느낌의바디에 더욱강력한AF모터에 Z마운트까지갖는다면..아..아님미다..ㅎㄷㄷ

Update - Nikon recently filed a patent for dual AF motors (thanks Broxibear):

Additional information on the different Nikon AF types can be found here:

"AF NIKKOR lenses use a mechanical coupling between the lens and the camera body. On several Nikon DSLR camera bodies, the focus motor is in the camera and a series of gears drives the lens' focusing mechanism, which allows the lens to focus.

AF-S NIKKOR lenses feature Nikon’s Silent Wave Motor (SWM). This technology converts “traveling waves” into rotational energy to focus the optics. This enables high-speed autofocusing that's extremely accurate and super quiet.

AF-P lenses use a “Pulse” motor or “Stepping” autofocus motor and are even quieter and smoother to autofocus than an AF-S lens, making these lenses ideal when shooting video with a DSLR."

I am not aware of another company that makes lenses with two AF motors - if I am wrong, please post in the comments section.
