[Leica] About lenses

Kyle,?
The Canon 50mm Serenar, although probably older than you are, is a fine lens. If it has served your needs for 15 years, why scrap it. Just take it to a good repairman for a CLR. Any of those listed on the LUG will probably so a fine job. I recommend Sherry Krauter, mostly because she lives near me. Lens CLAs are an easy job any should cost but a tiny fraction of a new lens. Keep it simple.

Hey folks ??

I have this Canon Serenar 50 I?ve been using for 15 years as my main lens and recently something weird happened, the focus hits a stop about 4mm from reaching the infinity stop. It happened once before, I was puzzled, and then ? it wasn?t like that anymore.?

Using my x-ray vision, I can see inside the lens and it just looks like a bunch of elves doing magic, but I have a vague thought that there might be a screw that marks the infinity point that?s come loose and sometimes sticks up too far.

I ordered a spanner wrench so I can open it up and look for something obvious, but apart from there being a loose rock inside the lens, or the maltise falcon, I?m not sure what to look for.

Any thoughts from the council of Wizards?

This might also be the universe telling me to buy a new lens.
