Subject: [Leica] fog up lens

Mike,

Thanks. I'll run the flash light test again with the lens stopped down.
Just in case the fog is confined to the front and rear surface, any good
recommendation on how I can get it off. I was tempted to use isopropyl
alcohol but was concerned it may do damage to coating. Wonder if you or
anyone on the list have any idea if it is safe to use alcohol?

TIA.

regards,
