Another adventure removing screws to see what happens. This is a bayonet mount Yashinon for the Pentamatic.  |

Yashinons are nice lenses - I hope there was something wrong with it !!

If there was something wrong with it, and you cured it, I hope it all went together again OK.

Dried up grease was the only problem. I dismantled it further to clean and relube the helicoid. There are multi start threads on both sides of the helicoid. I think there's about 15 ways to get it back together wrong! A very well constructed lens with some unusual details. Dozens of itty bitty ball bearings in the iris actuator/mount. I didn't take that apart!
It is now clean, relubed and back together. Can't test it as the body is really jammed up.
