I have a question about the focus smoothness (or lack thereof) on my pre-war 6x9 Super Ikonta. I purchased it from Certo6 via eBay last month. Everything seems to be in great working order, except for the focus wheel. It does turn, and it is actually smooth at the near and far ends of the focusing range. However, the middle ~ 30% of the focusing range is somewhat stiff. If I had gotten this in as-is condition, I would probably not even be worrying about it (at least, not until/unless it got much worse). However, I paid a CLA price for this thing, not an as-is price. Is it asking too much for the focus wheel to be perfectly smooth? I'm interested to hear the thoughts of those on this forum with much more knowledge/experience with these old rangefinders than I have.
