HAD to be his darkroom assist. from age 12 to 18...Left his equipment to me incl a set of SUN Aux Wide & Tele lenses... for his, now our, Rolleflex. Anyone know the exposure factor(s)???

    I have the Yashica branded aux. lenses and these are probably similar to the "Sun" lenses.

    Yashica has the following recommendations:

    WIDE ANGLE:
    75% increase in view
    Makes lens a 58mm
    Values on the focusing scale are halved
    Yashica recommended "best" apertures f5.6-f11

    TELEPHOTO:
    50% decrease in view
    Makes lens a 113mm
    Values on the focusing scale are doubled
    Yashica recommended "best" apertures f5.6-f11

    NB: no exposure correction needed for either lens

    When I use my WA adapter the 'wide open' pictures give kind of a "HOLGA" look without the shortcomings of a plastic camera. When stopped down past f11 the image gets better at the edges but you get the characteristic Diane Arbus vignetting which does not bother me. Have fun.
