    Thanks again,

    Yes, that is off axis light. There is frequently a black metal ring that is part of the uppermost lens group. It shines the light pretty brightly (as if it were a bright metal surface, even though it is black) on most of my older Componon-S lenses (and lenses of other brands to some extent). Just look up there (put you head down by the baseboard where the ring of light shines and look up into the lens) and you can see it. It is pretty obvious but not much to do about it.

    Thanks ic-racer, I think you're right. I'm hoping to find some way to flock (or similar) the interior so that this will no longer be a problem. My wife's work is such that we really need the enlarger to not have this issue.

    Yes, you really shouldn't bother - it is simply a random string - I use random strings for my usernames and passwords to lessen the chance of my accounts being compromised. (I'm a payment security professional by day.)

    Thanks all for your help and suggestions,
    John.

    Yes, this light is bright enough to fog paper if making big borders etc. You may just have to experiment with various lenses to find the best one. I have about 15 enlarger lenses. Seems the metal black bodied Componon-S lenses I have show brightest ring. The newer plastic bodied Componon-S lenses I just tested show the effect less.
