Re: AF-D

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


  • 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.

Ha, oops. Didn't realize I was stirring up some well-trod territory! Thanks for the resource.
