The Nikkor G lenses don't have aperture dials others do. For those that do is it only used when the lens is set to manul mode?

On digital bodies (and the most recent generations of Film slr's) the aperature dial is not used. You set the dial to the smallest aperature and aperature is then controlled by the camera body. You use the command dial to set aperature regardless of mode (including manual).

Thanks man. But then the question that follows is why a aperture dial on the lens?

That's how the older bodies worked
-> The aperture mechanically coupled through an outside ring to the meter inside the camera (and on some body a window on the viewfinder let you see the mechanical aperture)

With todays cameras, the aperture is set my the camera even in mamual mode.
Only when older manual focus lenses with no CPU are used would you use the aperture ring on the lens. But this would require a camera with an Ai coupling for metering or using an external meter.
