Using a self-made plastic spacing adapter, I am able to use my Sinar Copal shutter in front of my Chamonix's front standard with a lens mounted on the front of the shutter. Up to now only with (Multiphot) Micro Nikons that don't weigh enough to stress the shutter. Recently borrowed a large lens which was amazingly for it's size mounted on a custom Sinar lens board. Mounted it onto the front of the shutter but also mounted a "custom" supporter bracket based on part of a Sinar auxiliary standard to support it which is easily done on a Charmonix with it's multi female row of threaded "nuts" in its baseboard..
I know the Sinar shutter was designed to be used behind the Sinar's front standard but does anyone have any info on what the maximum weight of an optic to be mounted in front of the shutter would be? Or has anyone had any experience mounting lenses on the front of a Sinar Copal shutter?
In any case, a China seller on that auction site has been offering a metal adapter for mounting a Sinar shutter on the front of a Chamonix which I am seriously considering obtaining... again my adapter is a home made plastic one.
thanks
