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 most middle and big format lenses because of their lower resolution and lenses that have to be corrected by using glass elements in the mount adapter pieces (Canon FD and Minolta for example). These glass elements are often either low quality or the adapter itself is very pricey. You can use the cheap ones without their glass elements, but this will result in less working distance and loss of infinity focus. Since working distance is already very limited with macro lenses and loss of infinity not really makes sense for wide or tele lenses, this method is not considered a real option, when buying a lens for normal usage.
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 with M42 lenses).
Also, I don't make a distinction between fully manual and preset aperture mechanisms, they are just referred to as manual diaphragms.
3.) Asahi production periods: M42 preset Takumars 1957-1962, Auto-Takumars 1958-1962, Super-Takumars 1962-1971, Super-Multi-Coated (S.-M.-C.) Takumars early period and SMC Takumars later period of 1971-1976 (source: Frank Mechelhoff)
Pentax vintage mount versions: M42: 1957-?, SMC-M: 1975 -?, SMC-A: 1983 - ?
4.) Soligor series shorties: The C/D series was the top end line with some very good lenses. C/D stands for Computer Designed. The S/M designation seems to be a marketing gimmick like Vivitar's RL or SMS editions. S/M stands for Special Model/Sondermodell.
5.) A note on Vivitar serial numbers for lenses manufactured between 1970 and 1990 according to Stephen Gandy, complemented with information given by KironKid and Boggy at Kiron-Klub:
  They (most often) consist of 8 digits, whereof ...
  • 1st two digits tell the manufacturer:
    6: Olympus, 9: Cosina, 13: Schneider Optik, 19: Sigma, 22: Kino Precision, 25: Ozone Optical, 28: Komine, 32: Makinon, 33: Asanuma, 37: Tokina, 42: Bauer, 44: Perkin Elmer, 47: Chinon, 51: Tokyo Trading, 56: Kyoe Schoji, 61: Samyang, 75: Hoya Optical, 77: Kobori, 81: Polar
    - still missing in this list are #0 and #41
  • 3rd digit tells the year (so 5 either means 1975 or 1985 ... you need to know the production period to be sure)
  • 4th and 5th digit tell the production week
