For G-type Lenses we have a term and definition in Photography.

Nikkor AF-D lenses introduced in 2000. They don't have an aperture ring. Aperture setting is made through a "Sub-Command Dial" on modern auto bodies. G lenses were designed to weight less and be less expensive than their counterparts with an aperture ring. AF bodies without a "Sub-Command Dial" can use G-type lenses in Program and Shutter priority modes only. The first was the 70-300mm f/4-5.6G AF.
