I really don´t get it. You say I have a lead-free SE. And the version 504, right? But the changeover to lead-free glass happened first in 2002. If my SE is a 504, it can´t be lead-free according to your table..??! :eek!:
I bought it new from a small camera shop.
Yes it can be lead free. It could have been laying around the camera shop since 2002 or the outfit that supplied the camera shop with it could have had it since 2002.
