Hi, Is there really a way to distinguish between MOOSP ("15mm extension collar for TELYT 200cm") and FVOOQ ("Extension ring F, 15mm", for use with ZWTOO-ESUM), when they are unmarked? I'm asking because I have one of them, and it is unmarked, and I guess it could be either. You can see it in the picture below, 1st from the left. Since it was in a mix with a BOOQZ ("Extension ring B, 7mm") and a GVKOO ("Extension ring G, 30mm", not pictured), I'm going to assume that it is a FVOOQ. The 2nd from the left is also unmarked, but it looks (in height and threads (visoflex-to-visoflex)) very similar to the 3rd from the left, which is a BOOQZ (from the "B"). Could it be that? Any other opinion? The 4th from the left is completely unmarked. The male is for visoflex, but the female is too large do be either a visoflex or for the lens head of the Hektor 13.5cm 1:4,5 (the only lens head I have) or, I guess, heads of the same size. I do not know what it could be. Any idea? Thanks, Matteo
