Hello
I found these white spots inside a FSU Tair-11 133 mm lens. They dont have the typical look of fungus, as I have seen in my limited experience . Are they caused by fungus ?? Or is it something else?

and also some photos from a test roll with this lens. Images were not cleaned, they have some flaws, but they were made with the sole intention of finding some sort of flare. Most were shot almost against the sun or shiny surfaces. There may be flare (?) in pictures #6 and # 8 - but these restaurants were grilling food outside, there was smoke in the air…
I would like to have some opinions about these white spots and eventual measures to be taken – if any-
Thank you in advance

From the photo taken with the lens- seems like flare due to Haze in the lens. SO- I would suggest opening it up, and cleaning the surfaces.
Hard to know if this is dried moisture spots, or damage to the coating. Either way- I would expect it to come off with lens Cleaner, swabbed gently with Q-Tip and lens cleaning paper.

Thank you Brian.
Your opinion is important.
I will have an experienced professional to clean those spots. I won't dare to do it myself, some of the screws have their head sort of worn or deformed, I will cause more damage if I try to unscrew them. Moreover, there is a slght wobble of the diaphragm closing ring, maybe than can also de improved.
Best regards
