I just bought a used Noctilux 0.95 last week. Although it was used, it appears brand new, no marks, perfect glass, not even any dust. However, the focus ring is somewhat stiff. It's stiffer than my old f/1 Noctilux. I can still return it if this is not typical. I know that a new lens would typically be stiffer than one that's well broken in and I'm keeping that in mind. I realize it's hard to quantify what stiff means in a way that others can relate to without actually trying it in person but please relate your experiences if you own or have owned one. Thanks!
