Priority Mail just delivered my first Jupiter 12. Turns out it is a very attractive instrument, regardless of the fact that setting the aperture is a tad quirky.
As I fiddled with my new lens, I noticed the diaphragm blades seemed oily. Then, as I "exercised" the diaphragm, a tiny touch of oil appeared to be transferred to the inner surface of the front element.
How distressed should I be at this? My guess is that the speck of oil is not large enough to degrade the image but I hope it doesn't get any larger.
I've never experienced an oily diaphragm before in 50 years of shooting pictures. Incidentally, the lens was purchased from a reputable dealer in the States so I am not concerned about being ripped off.
