Originally posted by hinman Thanks for the valuable inputs. Your picture is lovely especially in the black color. My copy has a bit of oil on the blades and it is kind of awkward to operate the aperture ring and the extra ring that opens up the aperture ring in reverse direction.
Yeah. I've actually had two copies of this lens, one a black one that looks like the one you posted, the other an early production m39 mount lens with a silver metal body.
The newer black one had clean blades and a correct aperture ring, but it lacked optical coating and the color tone didn't look close to accurate (too yellow, not enough contrast and some ghosting). The older silver lens is the one I kept because it produces absolutely beautiful images ... but it has oily blades and the aperture ring is reversed (f16 is actually f2 and f2 is f16).
Still, there's something about this lens that prevents me from getting rid of it.
