I recently sold an older lens through the forum but when the buyer received it he advised me that it had fungus. I immediately refunded the purchase price and had him send the lens to Eric for cleaning. How can I check my other lenses to see if they too might have fungus? Not sure what to look for...

If you google around a bit, you'll find quite a lot of information... hope this helps "What Is "Lens Fungus"? Can It Really Affect My Camera Gear?" by Gene Walls | Redbubble

I don't believe fungus is catching, so your other lenses should be fine, but...

It's the conditions in which the lenses are used/stored that can induce growth of fungus.

The fungus spores are all around us, all the time, but only become a problem when given the right growth conditions - warm, humid/damp, and dark - that's why if you can you should store your lenses somewhere dry, airy and cool.

As to what to look for, normally thread like shapes on the surface of the internal glass. Hold the lens up to the light with the aperture wide open and look though it. Fungus tends to start around the edges and work it's way inward, so move the lenses around as you look through it.

Get real. Lens fungus grows on lenses and is a "specialist" and is, when present, a prove-positive of contagion. Treat it like a disease as it fully deserves.

Sorry to be so blunt, but it is not worth taking chances.
