What fogging?

Cheers, Paul.
Eh? Assuming you are serious - the fog which many lens users cannot see, which is not apparent if you view a lens by reflected light (light source on the same side as your eye) but which is revealed in its full definition- and contrast-sapping horror when you shine a torch through the lens, and which takes quite a few $$$ to get rid of. If you use only modern equipment and store it correctly, lens fog will hardly be a problem, but if you like to explore the qualities (which are many) of older lenses, you will soon find out what lens fog is!
