# Nikkor

Nikkor is the brand of lenses produced by Nikon Corporation, including camera lenses for the Nikon F-mount and more recently, for the Nikon Z line of mirrorless cameras.
The Nikkor brand was introduced in 1932, a Westernised rendering of an earlier version Nikkō (日光), an abbreviation of the company's original full name Nippon Kōgaku ("Japan Optics"; 日本光学工業株式会社). (Nikkō also means "sunlight" and is the name of a Japanese town.) In 1933, Nikon marketed its first camera lens under the Nikkor brand name, the "Aero-NIKKOR," for aerial photography.
Nikon originally reserved the Nikkor designation for its highest-quality imaging optics, but in recent history almost all Nikon lenses are so branded.
Notable Nikkor branded optics have included:
* F-mount lenses for 35mm SLR and DSLR photography (for a full list see Nikon F-mount).
* Z-mount lenses for Nikon mirrorless cameras.
* 1-mount lenses for Nikon 1 series cameras.
* Lenses for Zenza Bronica and Plaubel Makina medium format cameras.
* Lenses for Nikon S-mount and Leica rangefinder cameras, as well as very early Canon cameras.
* Amphibious lenses for Nikonos underwater cameras.
* Macro lenses under the Micro-Nikkor designation.
* Lenses for large format photography.
* EL-Nikkor photographic enlarger lenses.
* Microscope objectives.
* Industrial lenses, including lenses in support of the Japanese war effort during World War II.

## Lenses for Nikon systems
### Nikon Z-mount

Nikon introduced the Z-mount in 2018 for their system of digital full-frame and APS-C (DX) mirrorless cameras. All of Nikon's Z-mount lenses are Nikkors.

### Nikon F-mount

Nikkors constitute the majority of lenses available for the Nikon F-mount, which is itself the largest system of interchangeable flange-mount photographic lenses in history. These lenses are designed for the 135 (35mm) and Nikon DX formats. Over 400 different F-mount Nikkor models are known to exist.
* F-mount Nikkor lenses from various decades
* Pre-AI Nikkor-S 50 mm f/1.4 (A-type, 1960s to early 1970s)
* Pre-AI Fisheye-Nikkor 16 mm f/3.5 (K-type, early 1970s)
* AI-S Nikkor 50 mm f/1.8 (AI/AI-S type, late 1970s to mid-1980s)
* AF Nikkor 85 mm f/1.8 (AF type, mid-1980s to mid-1990s)
* AF-S DX Micro-Nikkor 85 mm f/3.5 VR (AF-S type, mid-1990s)

### Nikon 1-mount

Nikon introduced the compact mirrorless Nikon 1 camera system using 2.7x-crop sensors in 2011. The Nikon 1 system was effectively discontinued in 2018 with the introduction of the full-frame Nikon Z system.

### Nikonos

The original Nikonos system introduced in 1963 is a scale-focus and rangefinder system for underwater photography. The 1992 Nikonos RS system is an underwater autofocus SLR system based on the F-mount.

### Nikon S-mount

Rangefinder camera system dating to the late 1940s which became popular with the 1951 Nikon S.

## Lenses for other camera systems

Note: In the case of the Nikkor wides, "W" just means "wide". Prior to approximately 1976, most Nikon lenses had a suffix appended directly after the "Nikkor" name that was used to denote the number of optical elements in the lens design.
| No. of Elements | Designator Letter | Origin of Designator |
| 1 | U | "Uns" |
| 2 | B | "Bini" |
| 3 | T | "Tres" |
| 4 | Q | "Quatour" |
| 5 | P | "Pente" |
| 6 | H | "Hex" |
| 7 | S | "Septem" |
| 8 | O | "Octo" |
| 9 | N | "Novem" |
| 10 | D | "Decem" |
| 11 | UD | "Uns" and "Decem" |
For example, a lens with eight elements would be marked "Nikkor-O", and a lens with eleven elements "Nikkor-UD".
