I somewhere, probably here, saw some mention of the USSR Jupiter lenses, the 85mm one and a 135mm one. I checked them out on eBay and see that at least the Jupiter 9 85mm is pretty pricey for a lens of variable quality. The Jupiter 3 50/1.5 is also expensive, but the 50/2.0 is cheap. Does anybody think these are better than the usual Japanese lenses, such as the Takumars, Nikkors, Rokkors, and whatever in the same lengths? The aluminum silver Jupiters would look really cool on a silver E-PM1 though. And I read that they are light for an all metal lens. Their M39 mount is not quite the same as a Leica M39? Is that true?
