Since the AF-D discussion has started again, here is a useful resource:

http://www.photosynthesis.co.nz/nikon/lenstype.html

  • AF - Auto focus (1986)
  • Lens focused by motor in camera, 5 CPU contacts on lens mount.
  • D lens (1992) - Transmits focus Distance for improved flash metering.
  • AF-I (1992) - Telephoto with Integrated AF motor, 10 CPU contacts, manual override of AF.
  • AF-S (1996) - Similar to AF-I with improved Silent Wave motor.

The point here is that D lenses can also be AF-I or AF-S lenses, with internal motors.
