General Notes:
1.) I try to keep this list 'reasonable'. It is therefore limited to lenses, that can be adopted to Canon EF by means of still making sense. That excludes collector's madness targets, lenses without aperture ring and lenses that need custom manufactured adapters or modification.
2.) Limited EOS compatibility: Useless to say, all lenses in this list are limited in their EOS compatibility. There will be no AF nor In-Focus-Indication and there will be no time priority nor full auto mode due to missing electronic coupling between lens and body. Auto apertures are not available (while this feature will still be very useful for manual focusing).
Also, I don't make a distinction between fully manual and preset aperture mechanisms, they are just referred to as manual diaphragms.
3.) For even more specialized special application lenses see the Macrolens Collection Database.
4.) For more Nikon related stuff visit Roland's Nikon Pages. In-depth information like model variations, SN ranges and production periods here is given according to his information.
