hi friends!

i need a 75mm for my sinar P.
do you think it's better a lens with its own shutter (copal-compur-prontor)
or a lens DB mount (with sinar-copal shutter)?
i have some sinar shutters therefore it's not a problem.
but i think the rear+front+shutter thickness 'll limit camera movements
(tilt and swing).
at present i use a gradagon 65 4.5 with compur 0 on recessed lensboard, and a 90 4.5 with compur on standard lensboard.

thanks in advance.
