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.

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. Similar technology (2 AF motors) already exists in selected lenses from Sony, Leica, Fuji and Olympus.
