I have it and the S-M-C.
I've not had it apart, so it's possible that something could be loose. |
On mine, I feel a some lash in the helicoid, I don't normally feel any in any of my Tak's.
I also feel/hear a transition between 10 and 9 inch when racking the focus, anyone else? |
Yes, both of mine are the same. Both had very little wear. I sold them, kept the S-M-C 100/4. Iirc, closer than 9-10" the magnification is into range between 1:2 and 1:1. |
Thanks for confirming yours is like mine, I now don't have as big of a desire to open it up, the helicoid could be a challenge.
Edit, I spoke too soon, today the transition was between 8 & 9 inches, so I kept trying it, and it was slowly moving towards MFD... sigh.
Edit 2, now its back down between 8 & 9.... looks like I may be diving in after all... |
After remove name ring, screws surrounding front element, there are two sets of three screws, on some of my copies had loosened from much lens focusing, making action somewhat sloppy -- easy to check & tighten if necessary. _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮
