I have an old Canon FD 35-70mm 2.8-3.5 for my F-1 that has developed a problem. The internal zoom portion (the overall outer length of the lens is fixed, the zoom portion moves internally) has become loose so that if the lens is pointed straight up in the air, then rotated down toward the ground, the internal zoom portion will drop down (move forward)) about 1/10", with a clunk sound. It's like the tension that secures the zooms helix has loosened. I would like to get this repaired, but in nearly 50 years of Canon ownership I've never had to have a piece of Canon gear serviced and don't know who performs vintage Canon service. Any ideas as to the problem with the lens and suggestions as to who to contact for service?

Given the prices I found looking quickly on ebay, just buy a replacement.

I don't know if this guy on Ebay is BS or it's true that's most of the lenses are that way?

Your lens is not worth the cost of repair. Just buy a replacement lens on eBay. It will be cheaper than the cost of repairing the one you already have.

Absolutely agree. My personal preference for my all round 'Go To' lens was the Canon FD 35-105mm/f3.5.
You want to get the early all metal version. It was a workhorse.
There are a few listed on eBay, even a new one in the box. Here is a reasonable example.
