Hello
I am trying to understand the difference between D and G lenses in layman's terms. I understand they are exactly the same except the G lenses have no aperture ring on the lens itself. BUT what does this really mean when your using a D610 body? How does it change how you use your camera/lens and take photos?
Cheers and thanks!

In the context of the D610, it does make a difference but only in the sense that with G lenses, you have no choice but to use the body to adjust your aperture setting.

How big an impact that is probably depends on how accustomed you are to using the ring as opposed to using the body to change your aperture.

G lenses provide distance information, so G lenses are D, too, though it is not mentioned as part of the product name. (The difference between an AF lens, and an AF-D lens, is that D lenses send additional information to a flashgun used in the various TTL modes.) As the previous reply indicated, on a practical level, G lenses require the camera's controls to set the aperture. A lens labeled AF-D, or merely AF, has an aperture ring, allowing the choice of using either method to set the aperture.

This is a limitation for those of us with older-design cameras, such as my FM3A; I cannot set the aperture of my 50mm 1.4G lens if I affix the lens to the FM3A body, as the G lens lacks an aperture ring, and the camera lacks electronic controls to set the G lens' aperture.
