Nikon D vs G Lenses
Nikon is one of the most trusted names when it comes to photography. They produce some of the best DSLR cameras available today. But as important as the cameras, are the lenses that you use with them. Among the many types of Nikon lenses are the D and G lenses. The main difference between the D and G lenses are their ages. The D lenses are the older lenses that were created for SLR cameras that do not have certain features. The G lenses were created to compliment more modern SLR cameras that have more advanced features.
The feature that G lenses complement is the ability of the camera to dictate the aperture. Cameras that were meant to accept D lenses do not have this ability and relies on the manual manipulation of the lens to achieve the correct focus. To lessen the impact of new technologies to photographers, Nikon implemented backwards compatibility with their cameras and lenses. You can still use your older D lenses on cameras that are meant to use G lenses. But even if you have a modern camera, you will still need to manually set the focus if you use the older D lenses. This is because the D lenses do not have the mechanisms needed by the camera to change the aperture.
In order to focus D lenses, they have a focus ring that can be manipulated just like the zoom; you change the aperture by rotating the ring around the lenses. G lenses do not have a focus ring as there is really no need for it anymore.
Although D lenses are older and less convenient than the more modern G lenses, some people still like to use them once in a while. The D lenses can be used to create old style effects by the manipulation of the focus ring to achieve photos that are not totally in focus. There is really no point in getting D lenses if you have the choice. But if you already have them, you can still use your D lenses with your modern cameras that are equipped with G lenses.
Summary:
- Nikon D lenses are older than the G lenses
- Nikon D lenses cannot be focused automatically while the G lenses can
- Nikon D lenses have a focus ring while G lenses do not
