    Leica lenses - 3 Cam, ROM - need help

    Hi,

    I'm about to sell all my Leica R lenses including 3 Summiluxes. While trying to research current values I hit a snag. I don't know the difference between 2 and 3 cam, ROM etc. Google hasn't been able to help me either. My 35 Summilux has a row of contacts on the lens mount, so I think that might be a ROM lens, but the 50 and 80 do not. So that still means they could be 2 or 3 cam lenses?

    Can anyone help?

    1 cam: for the original Leicaflex
    2 cam: for the Leicaflex SL & SL2
    3 cam: for later R models
    ROM: for activating some functions on the R8 & R9

    Contacts mean a ROM lens.
    2 cam lenses have 2 silver coloured "ramps" around the rear element.
    3 cam lenses also have a 3-stepped black ramp in addition to the silver ones.

    1 & 2 cam lenses have a more limited market.
    Short version, if they meter at full aperture on an R3 - R9 body, they are *not* 1 or 2 cam lenses.

    Apparently there are also "3rd cam" lenses which only have the black staggered ramp & not the silver ones (not useful for Leicaflexes, as are the ROM ones).

    If you can meter with those lenses without closing the diaphragm using the depth of field preview: in other words, if they work when you meter "normally".
