This sale is for a very good condition Mamiya 645 55mm f2.8 S lens, including both caps.
There are obvious signs of use with a few tiny cleaning scratches on the front element (not optically significant) and there is alos a faint rub mark on the rear element coating (but this is not actually scratched). Otherwise this lens has great glass. Mechanically the click stops more continuous than “click” – but apart from this everything works as it should.
This is the very highly regarded S model – the later much improved N version optics in a metal body – perhaps the best combination you can get. This one has been heavily used but still does the job. Far cheaper than a perfect example!
