Pros: absence of distortions

Cons: "ancient" anti-reflective treatment, inefficient possible mating problems with sensors, if the adapter ring transmits reflections

Opinion: It's a lens that I've used for many years with my film Topcons, with which he has always behaved well. In particular, in architectural photos, it has never exhibited distortions of straight lines, which is common for these focal points. I put it to rest with dSLRs, because for draft reasons it was unusable, I "resurrected" it with the ML (Sony A7II). It is critical the choice of the ring, which must absolutely avoid reflections inside (finishing strictly more than opaque), worth the destruction of the detail, especially at the edges, if it does not diaphragm abundantly (11-16). Found the right ring, I managed to use it correctly, keeping in mind the limitations: it is a dated lens, with an ineffective anti-reflective treatment, which causes a lot of flare in the backlights, designed in an era when the photos were essentially in B&Amp;A N, its color yield is a bit unbalanced on the "hot", when compared with more modern optics, but nothing that can not be fixed in PP. Being an optic that I already had in the house, I consider myself satisfied, but if I had to buy it on purpose at 2-300 euros (price at which I see it often offered), maybe I would have let it go, and maybe I would have taken something recently cheap, like Samyang.
