    Handa made RAF Biogon 38mm unit

    Hi all,

    I made a lens unit of Biogon 38mm f4.5 from a R.A.F.(Royal Air Force) aero lens.

    Lens unit I bought from eBay.

    Was required very, very advanced design capabilities and machining accuracy.

    Thanks.
    I will post some results about one month later, because I'm making a camera.

    that's an amazing bit of creation you have made! it is science expressed as an art.

    my skill level is dremel tool dabbling/vise grip clamping/taking "it" to a skilled repair person to undue my "doing".

    now, if you could conjure up with a visoflex for a mamiya6...ooh, those longer RB67 lenses.

    good luck and good hunting.

    breathe, relax and enjoy.

    Great work, I also look forward to seeing results!

    What was the net cost of this lens, for you to make it?

    This I like... it inspires me to go and tidy up the junk in my garage and get to work on finishing one of my many, many (MANY) uncompleted projects.

    I think it will have to be the wide angle 91/2" square camera with the 6" Ross lens, first
