Hi all,
I have to replace the 'Mamiya Diaphragm Aperture Control Lever Knob'...yes, on ebay sombody is selling it, due to broken attachment. Althought the front part of the lens unscrews easy form the sutter, I can't get tthe shutter fro the rear end, and that's (I hope) where i have to be to open up the shutter. Any experience here? Can you just enscrew it, or do I have to detach the focus mechanisme?
