These variations primarily address differences in electronic communication, aperture control, and autofocus capabilities.

One of the key distinctions within Nikon F mounts lies between purely mechanical mounts and those incorporating electronic contacts. Early F mount lenses are fully mechanical, relying on manual aperture control and focus. As autofocus technology developed, Nikon introduced electronic coupling to communicate between the lens and camera body, enabling features such as autofocus, metering, and electronic aperture control.

Major Variants of Nikon F Mount

  • Pre-AI (Automatic Indexing): Early F mount lenses designed before 1977. These lenses require manual coupling of the aperture ring to the camera body and lack the AI mechanism that simplifies aperture indexing.
  • AI and AI-S Lenses: Introduced in 1977, the AI system added a mechanical coupling lever to allow the camera to read the aperture setting automatically. AI-S lenses (introduced in 1981) further refined aperture control with a linear relationship between aperture and diaphragm position, improving compatibility with some camera features.
  • AF (Autofocus) Lenses: These lenses added a mechanical autofocus drive system, with a motor in the camera body driving the lens focus mechanism via a coupling. Early autofocus lenses often lacked internal motors.
  • AF-S Lenses: Introduced in the late 1990s, AF-S lenses include a Silent Wave Motor (SWM) inside the lens, allowing faster and quieter autofocus without relying on the camera body’s motor.
  • G-Type Lenses: These lenses omit the aperture ring entirely, relying on the camera body to control the aperture electronically.
  • DX Lenses: Designed specifically for Nikon’s APS-C sensor cameras, these lenses have a smaller image circle and are not recommended for full-frame cameras.
  • VR (Vibration Reduction) Lenses: Incorporate image stabilization technology within the lens to reduce the effects of camera shake.

Compatibility Considerations

Nikon has maintained a high degree of backward compatibility across F mount lenses, but certain features may be limited depending on the mount type and camera body combination. For example:

  • Pre-AI lenses cannot be mounted on many modern Nikon DSLRs without modification.
  • AI and AI-S lenses will often function fully on manual and semi-automatic modes.
  • Autofocus may not function on bodies that lack a motor when using lenses without internal motors.
  • G-Type lenses require a camera body capable of electronic aperture control.
