Hi All,

I'm considering buying a used 70-200L f/2.8 Non-IS. It has dust and fungus inside the glass, and I'm wondering if I could pick it up and get it cleaned (and still save myself some money.) The seller want's $850 but they would also accept best offer, might be able to talk them down.

Does anyone have any estimates as to what the cleaning could cost? Once it's cleaned, it will be fine if I take care of it, right?

Thanks all,
-Mike

Dust is no big deal. Fungus is. I think I'd look elsewhere.

Thanks for the info. Any explanation you can offer as to why fungus is worse? I mean, I get the idea, something growing inside the lens, not good. But can't it be cleaned?

Fungus can be cleaned but it is much more dangerous because it's alive.
If you don't clean it properly, it'll grow again.
If you don't clean it fast enough, it'll etch the glass and infect other lenses.

My advice: stay away from that deal.


What we see depends mainly on what we look for.

How does the fungus get in there? I've always wondered that... especially since isn't that a weather sealed lens?

Even though it's weather sealed, it's not air tight; if the lens is stored in an area of high humidity, damp air will enter the lens, creating conditions that are ripe for fungus to grow.

Mold spores are EVERYWHERE.. It does not need to "get in" anywhere. Weather-Sealed or not!

The right conditions let the fungus grow... Mainly caused by high humidity.

Put any L lens into the right conditions for the right amount of time and you can grow your own fungus! :p


I believe you want to keep relative humidity under 60%, have good air circulation and even expose your lenses to the sun every once and a while. UV is good to prevent mold growth.

I believe some L lenses are UV coated out of the factory.

I'm interested in this as I will be sending off both my 24-105 and 70-200/4 IS as well as my 5d......24-105 for a cleaning, 70-200 for IS replacement and 5d for mirror upgrade. Gonna be an expensive package lol.

Okay, I've forgotten about it! Thanks for the strong piece of advice.

For those who find this thread in the future, does anyone know the price of a lens cleaning / calibration?
