My recently acquired Mamiya press camera (Early) has a problem with the Lens lock out.
Its the 90mm Lens.
I assume there is some sort of Bearing detent that locks the lens out for normal use & in for bellows use.
It will do neither. seems quite slack, especially in the "Normal" position.
I have just fitted some new seals to the 120 back & would like to shoot with it.
Any suggestions?
