Lens Fungus Removal

3 months 1 week ago #736719 by Crazyguy
My sister just found some old cameras that our dad gave us a number of years ago.  These cameras and lenses haven't been used in 20+ years.  The problem is that a couple of the lenses have some fungus in them.  How can this stuff get removed?

You can remove the fungus simply by leaving the lens out in direct sunlight. The UV will kill the fungus.

The problem is that the etching that the fungus caused will remain, and there's not much you can do about that short of  replacing the affected optics.

I was going to recommend just drop off the lens at a camera shop to have it professionally cleaned out.  But Tcav brought up something I had no idea about!  Tcav - from your experience will that remaining residue be noticed in photos?

Like anything else on the surface of a lens, it will be out-of-focus but it will lessen the contrast, the degree of which depends on the extent of the etching.

I haven't had this nightmarish experience yet… fingers crossed!

Light is free… capturing it is not!
