QUESTION: bayonet- and breech-mount lenses interchangeable?

    Hi, a newsgroup newbie here...

    I have a Canon AE-1 Program whose existing 50 mm lens is a bayonet-mount. I was
    looking for a 28 mm lens on Ebay and found what looks like a good one, except
    that from the photo it looks like a breech-mount. (I can't reach the seller in
    time to ask before the auction ends.)

    I remember reading somewhere that breech- and bayonet-mount lenses are
    interchangeable, but I have my doubts about this. Little help, anyone? (The
    auction closes in 50 minutes...yes, I'm cutting it close.)

    Thanks!

  2. Yes, any Canon FD (breech or bayonet), FL or R-mount lens will mount on
    your AE-1 Program. You'll probably be happier with the automatic
    diaphraghm of either version of the FD mount. Most used Canon pre-EOS
    lenses are FD anyway. Some folks prefer the breech. I have both and find
    the bayonet more convenient, but it's not that big of a difference.

    Thanks, Drew. I was thinking that the seller was actually selling a
    bayonet-mount after all, because the ring at the juncture of the lens and the
    camera body was black plastic, not silver (as I understand most Canon
    breechlock mount lenses have), but you've reassured me that it really doesn't
    matter. Unfortunately, I've lost the auction after a spirited bidding war, but
    I guess the other guy just wanted it more than I did! (Thanks again.)

    Any Canon FD series lens, whether breech mount or bayonet mount will
    work perfectly on your AE-1 Program. The only difference between the
    two mounts is the design, the old FD series use the collar ring
    breechlock system, and the new FD's use the bayonet system, but they
    both mount properly and work the same on all the A series (AE-1/P,
    A-1, AL-1, AV-1, AT-1), F series (old F-1, new F-1, FTb, etc) and T
    series (T50, 90, etc...) cameras bodies.

    If it was a black ring, it was NOT a Canon brand lens...most likely an
    aftermarket lens. If it did NOT have a ring, then it may well have
    been a new FD lens, but some aftermarket companies also used the
    bayonet mount for their FD compatable models, whereas some used the
    breechlock.

    There a damn sight better than what's available today! I'll take
    "muzzle loading" over point-n-shoot any day!
