Lens CLA

[chris_chen]

I have several vintage chrome lenses that I am not satisfied with cosmetically. Although, they produce good results, I keep a lingering thought that they might be better is the slight fogging were gone.

 

<p>

 

Once a CLA is done, does the fogging return after some time, or do the various tech's replace all of the lubricant culprits(?). Are there any other causes for the surface fogging of the older lenses?

And no, I do not believe in glass/MgFl coating deterioration/degradation, being chemically inert.

I had two lenses CLA'd by The Focal Point recently. I can not attest

to the durability of the cleaning, but the lenses look better

internally. I had a DR cron CLA and the front element recoated, and

a 3 element Elmar CLA'd. It cost me $250.00 for the DR and $85.00

for the Elmar.

BTW, for more info on "The Focal Point" and also lens CLAs in general,

see the following topic in the FAQ at:

My strong suspicion is that the fog won't return (of course it

depends on who does the CLA), or if it does it will probably take the

same 40 years.

Or even longer in a smoke-free environment? (Just some wishful

thinking.)
