E-type lenses feature electronic diaphragm control, severing the physical connection between aperture lever and camera of older lenses in favour of a completely electronic system.
E-Type lenses provide faster, more accurate aperture actuation allowing higher frame-rates when shooting in shutter priority modes. Please see earlier entry for PC lenses to get the lowdown on the perspective control process.
G-lenses have no physical aperture ring, the aperture of the lens can only be altered through the camera body. G-lenses can be mounted onto manual focus bodies but the shooter will be unable to change the lens aperture. Elements within the lens barrel move to acquire focus allowing for lighter more compact lens designs and faster autofocusing speeds. Some lenses like this are IF lenses, without carrying the IF designation in their title.
Confusing, I know. Lens groups move independently during focusing to maintain optical performance in close focus situations by using a floating element lens design. Nikon used the CRC system is used in fisheye lenses, wide-angle lenses, Micro macro lenses, and a few medium telephoto lenses starting in The profile of an aspherical element does not conform to the surface of a sphere. Aspherical elements are used to correct coma and various other types of lens aberrations but are costly and complex to manufacture.
Aspherical elements first began to appear in Nikon lenses in and some older lenses feature this designation externally. Modern-day lenses may feature the AS designation within the lens specifications, but it is not written externally on the lens anymore.
N lens elements are coated in nano-sized crystallized particles which dramatically reduce inter-element reflection within a lens and also help reduce ghosting and flare which can be problematic in wide-angle lenses in particular.
Not used in any modern Nikkor lenses and few older ones. In my research, I struggled to find any example of this kind of lens, although Nikon does still list it in their official acronym list. If you know of an RF lens, please leave a comment at the bottom!
Capable of compensating for up to 3-stops of movement when shooting handheld or in tricky lighting conditions. VR is extremely useful in situations where a tripod would otherwise be required. RD Lenses feature aperture blades designed to create a circular opening rather than the usual polygonal type.
This alters the appearance of bokeh in an image, the lack of straight lines creating a soft-focus effect. Normal mode means the VR interprets both slow and broad camera movements; it factors in a normal amount of camera shake for hand-held work. When you turn on Active mode, it factors in a more pronounced camera shake—say you're sitting on an idling bus in traffic and want to take a picture.

Nikon has traditionally used the term AF in conjunction with another letter, such as D or S.
The majority of its current optics are AF-S lenses see below. These are designed to produce smooth autofocus during movie recording, as opposed to AF-S lenses, which were designed before video was made available on DSLRs. AF-S lenses can still be used to perform autofocus during video recording, just that they do not manage to do so as discreetly as AF-P lenses. AF-P lenses are not compatible with all Nikon bodies, and firmware updates may be required with bodies that are technically compatible, in order to make sure this is the case.
Older range of Nikon lenses D denotes that a lens communicates information about the subject to camera distance to the camera.
As with more recent G-type lenses described below , this is used for the purpose of metering and flash exposure, although D-type lenses almost always have a physical aperture ring around their barrel, whereas G-type lenses do not. Defocus Image Control. This rarely used term is found on lenses that allow the photographer to control the spherical aberration in the image by way of a special ring around the barrel.
