This Pro 120 back HA401 for the Mamiya 645 Super, Pro and ProTL cameras is in mint condition and perfect working order.
This back has absolutely minimal signs of use, and it works perfectly, including metering correctly with an AE prism (and a lot of the backs on eBay are faulty and will not let you meter with them – but I always test for this). The 120 insert is also in mint condition with minimal signs of use.
A great addition for your Mamiya 645 outfit – you can never have too many backs! 120 insert and darkslide included, plus the original box and instructions. You will not find a better example.
