Question about Quantaray 100-300mm F4.5-6.7 Zoom Lens for Canon AF
I have two Quantaray (Minolta) AF Electronic Telephoto Lens showing internal spider web like indications of, I presume, mold.
Is this an economically repairable problem or should I just "junk" them....?
It is lens fungus and you're correct in your assumption that it's uneconomical to professionally repair on your lenses. But it need to be pretty bad before it affects image quality so don't junk them just yet.
Some types of lens fungus can be killed simply by leaving the lens out in sunlight, but I'd suggest that it's better to leave them exposed to the indirect sunlight on a bright overcast day to prevent any chance of sharply focussed light burning the inside of the lens. Killing the fungus won't remove the dead stuff but it prevents the problem getting worse.

For Nikon AF and manual focus SLRs. The compatible T Mount System makes it possible to use most any single lens reflex camera in combination with various front camera attachments such as telescopes, mirror lenses and slide duplicators. The T Mount is a metal connector that screws onto the compatible front attachment and allows this combination to be coupled to the SLR camera lens mount.
