As usual, Darkly comes though with great service, Just got my new lens…Yay, and emblasering again soon!
But before I put the new lens in, there was a little orange oring in with the lens package that arrived in its cool little 3D printed container, what is that for??
Cant find it in any of the manuals or posts, is it supposed to go in with the lens? does it go in before lens or after lens?
Don’t want to damage new lens if it needs this spacer?
