    Is it possible to use a Copal 0 on Arca R-mount?

    I don’t have Arca R system, mainly due to the expensive lenses available to Arca R. I am think if I can use a Copal 0, I can use some cheap lens. The Arca R lens look just like a Copal 0 on a circular board with thread. But I don’t find the “board” sold anywhere. I wonder is it not possible...

    What is the distance from sensor to mount on a M-mount DB?

    I am thinking of converting a V-mount camera into M-mount, due to the inventory of DB. I measured the distance from ground glass to mount on a V-mount ground glass. It is 3mm.

    What is the max speed of leaf Aptus with Hasselblad lenses?

    I just got a Leaf Aptus II and Hasselblad 50mm CFi. When I tested the combination with a sync cable connecting the lens and the digital back, I noticed that the shutter speed can only goes to 1/30. If I use 1/60, the digital back will get a black image. I wonder is this expected?
