This very rare Mamiya 645 Pro 135 back HC401 for the Mamiya 645 Super, Pro and ProTL cameras is in really excellent condition and perfect working order. The instructions can be found in the Downloads section.
This back has only normal very minor signs of use, almost near mint, and comes complete with the usually missing panoramic mask. Also tested and working perfectly is metering with an AE prism.
No problems at all with this back!
A great addition for your Mamiya 645 outfit – you can never have too many backs! 135 insert and darkslide, plus the panoramic mask included.
