    For those who have experience or seen lens fungus and haze;

    Take a look at the following pictures of my lens - I took them in front of a table light.

    It's an old Soligor lens so I expect and have always seen some dust - but on really close inspection I think I have something else going on.
    Before I took these pictures I cleaned the front and back glass with a "micro fiber" cloth.

    In this picture, is that haze on the perimeter between 6 o'clock and 9 o' clock?


    Here's another one from a similar angle.


    Other side looks much cleaner...


    I'm also concerned about the spot at around 8 o'clock in this picture. Is that fungus?


    I would appreciate any input.

    After reading that article I would conclude that my lens is pretty clean - especially considering it's age.

    Am I kidding myself?

    That doesn't look like fungus to me, just dust. The fungus that I've seen usually has some sort of "feathery" pattern to it.

    What David said. You've just got dust. And not much, either. Most fungus is looks like feathers or spider webs.

    Here's what fungus looks like on the front element of my Canon FD 135mm f/2 before I cleaned it:


    And after, just because:

    The original pictures look like maybe just dust. I hand fungus in a lens once and it made very distinguishable "root" like pattern in one spot on the glass.
