Filters

I have a number of unused Russian camera lens filters.
Size 33 x 0.5 XC10; OC12; XC17; KC11; X3C9; XC12; XC18.
Size 40.5 x 0.5 X3C-5; HC-2x; HC-4x; XC10 for Lada +2 +3 and +5 dioptre;
Size 49x0.5 XC18; XC17; KC11; OC12; XC12; X3CP.
Ј5 each plus postage at cost.

Richard, what are type of filters are the 40.5mm ones and have you any idea if any of them are multicoated?


Do I take it that the XC-10 are actually close-up lenses that go on the front of the main lens, rather than eyepiece correction lenses?
