Mamiya 7 80mm Lens: Drying Out Moisture Inside the Lens

This Mamiya 7 80mm lens was subjected to moisture. Fortunately, no damage to the shutter. After removing the lens group and some disassembly and cleaning, the shutter and lens elements were then put into a low humidity chamber for several days to make sure all traces of moisture were gone.
Photo two shows the moisture in the lens before servicing. The third and fourth photo show one of the Mamiya lens removal tools that I use when working on Mamiya lenses. While I do have many adjustable spanners, I feel that using the factory tools makes the repairs go smoother.
