    Yes, but what if I have to replace the original Compur 3 shutter with the f5.6 version? I open the iris to its max. e.g. f5.6.

    The Rodenstock Eurygon is a Triplet lens.
    The opening of the SINAR shutter is 76mm, e.g. it is 10mm smaller in diameter than the Eurygon. Wouldn't the SINAR shutter cause vigentting in this case?

    Re: Goerz Dagor F6.8 Series III no.3

    I hope it's not a lousy dagor (especially it is not a 'Berlin Dagor').

    I assume the lens was mad between 1906 and 1908 - the shutter might be from a later date (I'm OK with that).
