    Hi Carfin, the "KF" marking is for Kältefest (cold weatherproof) and that Invarol grease used inside the binos.

    "O": a light blue circle indicates Grease no. 1416 which would work down to -40 deg c.

    A blue cross indicates Grease no. 1442, again supposedly functional to -40-deg C

    The triangle again refers to the type of grease used: in this case the later improved type of grease.

    Hope this helps?

    Cheers, Ade.
