This sale is for a really good condition Mamiya 645 45mm f2.8 S lens, including both caps.
This lens is cosmetically excellent other than the usual paint loss on the rear mount, and working perfectly. There are only normal minor signs of use other than a faint scuff on the lens coating in the centre of the front element. This has no real effect on use; it MIGHT cause a bit of flare if shooting directly into the sun but otherwise you will never notice it – but its there so the lens price is reduced because of this. This is still a great lens, equivalent to 28mm in 135 format.
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.
A great lens, and the model I choose to use myself.
