When inspecting a 2nd hand lens, I'm wondering if we can tell whether a lens has been cleaned to remove mould.
Thanks

yanyewkay said:the prob is that the mould will surely manifest itself onto the micropores of the glass surface (something like that) and will grow again once the coniditions are right. So keeping it in the dry box should be good practice.
yups quite true about the pores in the air part but the myth that using it everyday will not get fungus is not true. I think there was a post in CS quite some time back about this journalist that uses his equipment everyday but had a good harvest of mould in his lenses as well.. The mould may not grow on the surface of the lenses that are used everyday but the inside is a nice place to settle on.litefoot said:Pores are all over the air. I am sure even an unopened lens are subjected to the risk of fungus infection in humid atmosphere. Only way to prevent it is to use it often and keep your equipment in Dry Box for long storage.

Is it true that Tamron lens is more resistant to mould/fungus than Sigma lens? I hear this from the camera shop seller. It could be his trick to push me buy Tamron over Sigma (because he is out of stock of Sigma lens, the model that I am interested).
Anyone know something to share?
Thanks!
