  1. Hi all.

     

    I just purchase a rollei electronic shutter 0,is ready change my copal 0 shutter.But i find rollei larger volume than copal.The thickness of the two is also different.Rollei 0 rear bayonet size 7mm larger than copal 0.

     

    So i have two problems

    1: If i need much gasket at front lens group ? I don't want to lose my infinity.

     

    2: How to solve the problem that the rear bayonet is bigger than the standard copal 0?

     

    3:I compare the rollei 0 with schneider shutter 0 at F5.6, it seems rollei 0 aperture caliber is more large than schneider.Where mistake ? How to modify lens initial minimum aperture at rollei 0 shutter at rollei control s ?

  2. Hi all,

     

    I just buy a copal shutter size 0, i find the aperture pole can not stop at each aperture scale like F5.6-F8-F11-F22 and so on.

    I check this use with my schneider digitar lens ,each of them can stop at each aperture scale and fixed at it if you not keep on rotate the lever.

     

    If anyone know of this? Can i modify my Copal 0 shutter?
