Nikon’s AF-P 18-55mm Lenses Pack Stepping Motors for Quick and Quiet Autofocus

Nikon today announced two new 18-55mm kit lenses for entry-level photographers. They're the first AF-P lenses from Nikon, with the "P" indicating that the lenses use a stepping motor for fast and quiet autofocusing.

There are two variants of the new AF-P DX Nikkor 18-55mm f/3.5-5.6: a VR one with stabilization and a non-VR one that leaves it out.
