What’s the difference between D- and G-type Nikon lenses?

Jason says... The most obvious difference is that D-series lenses have a manual aperture ring, whereas newer G-series lenses don’t. You can therefore only set the aperture of a G-series lens from the host camera, rather than on the lens. It’s not an issue when shooting with a Nikon D-SLR, where the aperture is adjusted via camera controls anyway.
Another difference is that D-series lenses don’t have a built-in autofocus motor, instead relying on a motor in the camera body. Recent entry-level cameras like the D3300 and D5500 don’t have an internal motor, making autofocus impossible with D-series lenses.
