Canon Serenar 85mm f/2.0 Clean, Lubricate, Adjust (CLA)

Pic 1

This Canon Serenar 85mm f/2.0 is in excellent condition, but has a bit too much drag on the focus ring and some oil on the aperture blades. I know with a CLA it will operate smoothly and more freely.
For an 85mm lens it is long, but has a small diameter. It’s also very heavy, being made almost entirely of brass. There are no plastic parts on this lens.
There are a lot of little screws to keep track of. The set-screws come in groups that aren’t necessarily the same size. Still, compared to other lenses this one is pretty simple.
You can read more about its history in another post.

Like I said, there are a lot of little screws, but overall this isn’t a very hard lens to work on. Just be careful because they are very old lenses and slightly rare.
If you liked this CLA be sure to read the other CLA articles I have. There are three of these Serenar lenses and a Canon FD 35mm tilt/shift.

  1. Your photos were very helpful in overhaulling my Serenar 100/4! The hardest part was reinstalling the little curved L-shaped brass piece under the focus ring. Thank you for this tutorial.
