    Isostigmar lens

    I pick up a unusual lens since I have not seen much about it here,
    Its a R&J Beck Ltd Isostigmar lens7.2 inch f-5.8
    also what is stranger is it has three set of Iris scales on the alum barrel
    the main scale is 5.8 to 32 but can go down 45.
    the other scales are F 16 to45 but will go one more stop on the scale
    the last set are b f 16 to 45 with one more on the scale
    I have a funny feeling this is a convertible lens F= front element, B=back element
    and then combined.

    The black and white shot at F-32+1

    enjoy comments welcome
