Meanwhile, the back channel speculation is about the “why” of the focus motor change. Nikon makes three claims about the focus speed:
(1) fastest focusing lens “When used with a camera equipped with the EXPEED7 image-processing engine”;
(2) “approximately 5x faster than [the original lens]”;
(3) “AF tracking during zooming has been enhanced by approximately 60%.”
I have to wonder if the move to SSVCM is partly in anticipation of the next generation of Nikon bodies. This is actually one of Nikon’s modus operandi: significant lens technology changes tend to precede camera technology changes. The reason why has to do with needing something to test a future camera against. You could, for instance, improve focus performance of the upcoming camera, but if the lens focus speed is the gating element, you wouldn’t be able to prove the new performance until such a lens is available. Nikon is first and foremost an optical company, so having lenses lead cameras makes a lot of sense.
