Thread: What should I do with this one?

  1. #1

    Cool What should I do with this one?

    I have a Wollensak 12 in "multi focal lens, barrel with iris, great big brass lens, in good shape iris marked in even numbers 4,5,6,7,8,9,10,11 and 11.7EX.

    I was going to use this on a project but it got put in a cabinet and never mounted. Looks like somebody could use it, but I have no clue as to who. (whom?)

    Those sound like Universal or 'U.S.' f/stop markings. That system was popular in the early years of the last century, '4'= f/8 as I recall. Not really my cup of tea, but of course there are many antique lens aficionados on this forum. Someone will know its actual age and lens design; and someone will want to use it, I'm sure.

    .... one of the "Beach" - modded lenses, it seems.... is it complete? Jim Galli had one once I think, in a shutter. See:
    https://www.photrio.com/forum/threads/wollensak-beach-multifocal-series-b.17396/
    Have you not tried it? Put it in the classifieds, if you want to pass it on. Not sure what its worth; I'd probably raise my hand if I could afford another lens to play with lol. ... someone else is bound to.

    The U. S. system of apertures started at 1 (f/4) and doubled for each one stop decrease in exposure. U.S. 4 therefore does equal f/8.

    Is this correct?

    1 - f4
    2 - f5.6
    3 - f?
    4 - f8
    5 - f?
    6 - f?
    7 - f?
    8 - f11
    9 - f?
    10 - f?
    11- f?

    Sounds like the crazy system than Schneider used on their M-Componons.

    The Uniform Standard (US) system is what Jim said (1 2 4 8 16 32 64 128 256 = f/4 5.6 8 11 16 22 32 45 64). The lens is not marked in US or f/ but in some other kind of system - probably a relative exposure time.

    I have an old compound shutter marked in linear numbers as Herb described and mounted in what may be part of a camera for optical experiments. That shutter isn't accessible now, but the numbers may be the aperture diameter in mm.

    Put that puppy on a lens board and she what she'll do!
    I steal time at 1/125th of a second, so I don't consider my photography to be Fine Art as much as it is petty larceny.
    I'm not OCD. I'm CDO which is alphabetically correct.

    Sell it on Ebay. Just say that it is rare and collectable and of course in mint condition.
