Series 8 filter on C 50mm


Active Member
I just received 2 series 8 filters to go onto
my C 4/50 lens.

They nicely fit in the shade, I am just wondering if there is a 'prefered way' of inserting them.

What I mean is this: the filters themselves have a threaded side which has a retaining ring to hold the glass in place. Does one put that side towards the lens' front element, or the other way around?

That is what I assumed, there is probably an approx 2mm difference in the frontelement - filter distance but that is all.

It was just one of these things that made me curious.

thanks, W/
