Lens For a Nikon N80


Hi all!
I have a question about lenses for my Nikon N80. I have been out of the photography loop for awhile. Someone told me I should buy a new camera because mine will not work with AI or AIS lenses. What is an AI/AIS lens?

Thank you!

  If you only use autofocus lenses with your N80 then there is no need to change bodies.

AI = Automatic Indexing, AIS = Automatic Indexing - Shutter. These designations, along with "non-AI" (the earliest Nikon F-mount lenses), refer to Nikon manual focus lenses. There is a mechanical connection between the camera body and lens to communicate the aperture setting.

With Nikon's autofocus (AF) lenses an electronic communication of the aperture setting was added. While some of Nikon's new autofocus cameras retained the ability to use the mechanical link with manual lenses, others like the N65 and N80 can only use the electronic connection. So while older manual focus lenses can be mounted on the N80 and used manually, the meter and autoexosure will not work with them.

  Thank you Jon! Just to make sure I get this right.... I can use any newer Nikon lens or equivelent if it is auto focus and everything will work right. But if I use older Nikon manual lenses, the camera meter and auto functions will not work correctly? (Did I get it?)

Thank you!
Shannon
