Nikon calls this the Nikon AF-P DX NIKKOR 18-55mm f/3.5-5.6G VR.
AF-S: Quiet focusing with a silent wave motor (SWM).
DX: Only works on digital cameras, usually gives black corners on film.
G: No aperture ring. Only works on cameras newer than about 1992.
VR: Vibration reduction, rated for three stops improvement.

f/3.5 - 5.6.
11 elements in 8 groups, including one hybrid aspherical element. A hybrid aspherical element is a glass element to which a thin aspheric plastic film is glued. This lets this $200 lens perform like a $2,000 lens. Nikon has been doing this for a decade, and their other lenses that use this technology are wonderful.
7 blade rounded.
Stops down to f/22-36.
0.9 feet (0.28m) from the image plane (the back of the camera). This is only inches away from the front of the lens!
