Hasselblad Distagon 40mm F4. Elements are spotless, I don’t see any hazy or foggy, see my description picture. I did find little usage see the closed up picture, and testing picture I use F8 with my Mamiya ZD jpeg for easy loading to eBay. The original hood I cannot find but this is the same one Hassel 40 printed on hood, I always feel it is hard to put it on the lens, so I use an aftermarket works very well and also this hood comes with a fitting cover. I will put them all when I ship lens out for the wining bider.
