This fast 35mm zuiko is in very good condition. There is some wear on the edges of the knurled aperture ring, but the lens looks very nice nevertheless. The glass is clear and the aperture blades are clean and they move well, the focus helicoid feels nice and the aperture ring clicks and turns nicely too. My original 35mm f2 zuiko (a different lens) is permanently mounted on one of my cameras, and has been for some years.  I was initially skeptical about the performance of this lens, thinking it was over-rated, but I've travellled to Europe twice with it and I'm so pleased with the photos it's taken, using it almost exclusively. It's now somewhat worn-looking and needs to be re-greased, but it just keeps rewarding me. So I won't keep this replacement lens which is in much nicer condition.
