>>3551517>I sell film cameras and repair lenses. Seriously have you even touched a Canon FD lens?
I have FD and FL lenses that I use on an AE-1 and adapted on an EOS M. No fungus. You can find these lenses all day long on eBay with no fungus.>>3551544>More than 3/4 of the Canon lenses with fungus have fungus that can't be removed.
Fungus can ALWAYS be removed. It's the etching into the glass caused by fungus that cannot be removed. This is the same for EVERY lens.>>3551544>Canon FD is prone to them as compared to for instance Nikkor
Look you literal fucking retard: ALL lenses exchange air with the environment they're in even while mounted. ALL lenses are wide open to air when dismounted. ALL lenses get fungus spores in them. Humidity determines if fungus actually takes root and grows. Canon physically could not be better/worse than anyone else here.
The most charitable explanation for your bullshit belief is that you really are a repairman in a humid area where most people who come to you have Canon FD glass, so you think that means something about fungus growth when all it really means is that more people bought Canon.
The more likely explanation is that you are a brand faggot making up FUD.
