The way lenses are made don't stop to amaze me. I've once visited Shott in Mainz/Germany and I remember their work around telescope lenses, just impressive. Excellent video thanks very much for sharing... The victory of man over material !

. . . .But you'd think with all that inspection that you'd get a clean lens! Unfortunately my 500/4 arrived with a load of dirt on one of the inside lenses. It's now back with Canon, hopefully it will arrive back clean in the next few weeks.
