    Re: G Claron 240mm f9

    Peter,

    I'm sorry, you have got the same problem as I have. I have a Copal 1 shutter with a Fujinon lens in it. My G Claron, which is a barrel lens, fits this shutter but the aperture now belongs...

    Re: G Claron 240mm f9

    Hello,

    I have measured the distance in mm from f9 at zero. I hope this answers your question.

    f9 0
    f11 7
    f16 13.8
    f22 20.3
    f32 27.0
    f45 33.2

    Andrew,

    Jody,
    Just when I thought my troubles were over. I do some woodturning and have a lathe, but I hesitate to start cutting into a shutter. I think I'll try it as it is and see what results I get.

    Re: G Claron 240mm f9

    Andrew,

    Yes you are correct.


    I have calculated the equivalent aperture for the G Claron when the shutter scale is at f 5.6, f8 etc.

    Clearly I cannot expect f5.6 because the G Claron max...
