Further notes:
• AF and AF new versions differ in that the AF version only has a narrow plastic focus ring, while the ‘new’ version offers a proper rubber focus ring. The ‘old’ version is minutely longer and lighter.
• AF new and AF-D versions are identical except that the AF version (without D) does not communicate distance information.
• These lenses (AF and AF-D versions) are fundamentally the same lens as the Nikkor Ai 24 mm f/2.8 (introduced 1977) and Ai-s 24 mm f/2.8 lenses (introduced in 1981).
• To improve close-up performance, Nikon used its floating elements, ‘close-range correction (CRC) technology.
• The dedicated lens hood is the HN-1 (thread mounted) but an OEM wide-angle hood for 52 mm threads is also an option.

A brief genealogy of Nikon SLR lens types

Nikon is undoubtedly one of the great names in 35 mm SLR photography. The Nikon F mount has been in continuous production since 1959. During that time, the mount has developed/changed in some detail, however without ever fully sacrificing compatibility.

In short (a longer version is here), the development of Nikon’s SLR lenses can be traced as follows:
• 1959–1977: Pre-Ai. Manual focus lenses that use ‘rabbit ears’ to communicate selected aperture with the camera body.
• 1977–1986: Ai and Ai-s. Manual focus lenses that may have ‘rabbit ears’ for backward compatibility, but are designed to communicate selected aperture with the camera body through indentations in base of aperture control ring.
• 1986–today: AF and AF-D. Autofocus lenses that do not have a focusing motor within the lens, but rely on the focus motor within the camera. All AF and AF-D lenses are simultaneously Ai-s lenses (they are Ai-s lenses extended with AF) 6
• 1996–today AF-S and AF-P. Autofocus lenses that have an internal focusing motor and do not rely on the body having a focusing motor.

Nikon has a long and distinguished history of producing 24 mm f/2.8 lenses.
• The first iteration (1967–1977, available in F-, C- and K-types) uses a 9 elements in 7 groups design.
• The second iteration (1977–2020, available in Ai-, Ai-s, AF- and AF-D types) uses a 9 elements in 9 groups design.

In 1977 Nikon also introduced a faster version (Nikkor Ai 24 mm f/2; data sheet here) that was upgraded to Ai-s spec in 1981 and remained in production until 2005.

The current AF-S 24/1.4 (2010–today), AF-S 24/1.8 (2015–today) and Z 24/1.8 S (2019–today) are based on more modern designs.


Besides adapting, this lens can be used natively on all current high-end Nikon dSLRs and several earlier medium-to-high-end older Nikon dSLRs. Moreover, if the camera body contains a slot-drive focusing motor, this lens will even auto-focus7. Likewise, if the lens has been retrofitted with ‘rabbit ears’, it can be natively used on all Nikon F-mount film cameras ever produced (without the rabbit ears, it is limited to post 1977 bodies).

Thanks to being a fully manual lens (manual aperture, manual focus), the lens can be adapted to all mirrorless cameras using a suitable dumb adapter (and such adapters are easy to find). Moreover, a large range of special adapters (helicoid adapters, tilt/shift adapters, speed boosters) for using Nikon F lenses on most mirrorless systems are available. Currently no adapters for mirrorless exist that would allow autofocus through the slot-drive screw.

Using Nikon F lenses on non-Nikon SLRs and dSLRs is likewise a distinct possibility. Thanks to the relatively generous flange focal distance of the Nikon F mount (46,5 mm), adapter rings for all dSLR mounts are available as well as for a goodly portion of film-era SLR mounts. Such rings will not allow autofocus, and are unlikely to support auto aperture, but even then the lenses can be used in stop-down metering mode.


1 Focal length is (unless stated otherwise) given in absolute terms, and not in Full-frame equivalent. For an understanding of whether the lens is wide/tele, see ‘Angle-of-view’.

2 Picture angle is given in degrees and concerns the diagonal picture angle. Rule of thumb:
> 90 ° ==> Ultra-wide-angle
70–90 ° ==> Wide-angle
50–70 ° ==> Moderate wide-angle
40–50 ° ==> ‘Standard’ or ‘normal’ lens
20–40 ° ==> Short tele lens
10-20 ° ==> Tele lens
5-10 ° ==> Long tele lens
< 5 ° ==> Ultra-tele lens

3 Length is given from the mount flange to the front of lens at infinity.

4 Diameter excludes protrusions such as rabbit ears or stop-down levers.

5 S=straight; R=rounded; C=(almost)circular at all apertures.

6 There is a further sub-class of AF-D lenses called AF-I lenses that are otherwise AF-D lenses (meaning, fully Ai-s compatible), but have an internal focus motor. Only long tele lenses were made in AF-I variants.

7 As of this writing, the following Nikon dSLRs fully support autofocus, aperture priority and manual metered modes on Nikkor AF/AF-D lenses: D2, D3, D4, D5, D6, D200, D300, D300s, D500, D600, D610, D700, D750, D780, D800, D800E, D810, D850, D7000, D7100, D7200
