The G lens doesn't have an aperture ring as the F lenses do.

Which basically means that in manual mode you set the aperture from the camera instead of the lens.

G lenses don't have aperture ring and don't have electronic diaphragm. E type lenses are not G lenses but don't have aperture ring and have electronic diaphragm.

That's correct. However, it seems to vary somewhat. I've some lenses with aperture rings the camera is the source of the setting, and some that I have to set manually using the aperture ring. In the case of the camera being the source, the aperture ring is locked at the smallest aperture.

"Finally, we end with the letter G, which indicates that the lens >>has<< an electronic diaphragm control, meaning that the f/stop is set from the camera. On older NIKKORS you may see the letter D, and that means distance information is factored into the metering process. These days all NIKKORS have distance encoders, so you won't see D on new NIKKOR lenses—only G.

The above is accurate, but an E lens takes it a step further.
Witn an "E" lens a specialized electromagnetic diaphragm [b]mechanism operates[b] in precise sync with the camera's shutter for reliable exposure control during high-speed sequences.

Although the article is from a Nikon website it is incorrect. The G lens aperture is controlled from the camera but via a mechanical level. Only the type E lens aperture is controlled electronically.

Or D lenses. Another difference between the Nikon 50mm D and G lenses is that the D lens does not have a focusing motor whereas the G lens does. For those cameras that do not have focusing motors the 50mm G lens would be required. For those cameras that do have focusing motors, the less expensive D lens would suffice.
