Hi everyone

I found that in many of my lenses there are dust or dirty in the inside of the lenses... How is it possibile? Is there a way to clean them?

Bye

As mentioned in another recent thread, moisture or oil can certainly get inside a lens, requiring professional disassembly and cleaning. Dust would be unusual, but perhaps the lens was used in an application where dust could be blown in, like a Century Cine-Focus blower. Or someone used high pressure air to try to "clean" the lens, forcing dust inside.
