That is not new to the 105 macro! That was my point. Nikon has touted this from 2018 for the Z lenses.

"The NIKKOR Z 24-70mm f/2.8 S incorporates an all-new multi-focusing system, consisting of two AF drive units precisely synchronized..."

The same is true of the 70-200 even though they don't state it on its page.

Nikon say several Z lenses including the 20, 24mm, 35mm and 85mm primes have a "multi focussing system".

What is new is mention of a newly developed stepping motor to help achieve "Extremely fast and precise AF control".

It is likely Nikon uses a different stepping motor in each lens.

It is also likely that faster stepping motors than when Z was launched 2.5 years ago are available.

Who makes the motors used by Nikon is another topic.

It seems it's not just hardware - but the software to drive the multi-focus system can seemingly be specifically tuned to a particular lens... this from the NikonUSA,com website describing the MC 105:

"The NIKKOR Z MC 105mm f/2.8 VR S is fine-tuned for close-distance focusing. A new autofocus algorithm accounts for minute distance changes that alter the effective aperture, maximizing the resolving power of the S-Line optics."
