    Actually what was confusing Dennis was the missing bits

    Leica screw thread lenses are M39, whereas Leica M lenses are bayonet. Either way some Leica lenses split to fit a Visoflex. The adapter in question is most likely for attaching an M39 lens to a Pentax 67 bellows for macro work, rather than direct to a camera body.

    The old 135 Hektor (and 90mm Elmar?) will cover 6x7. The head of the lens unscrews. These aren't telephoto lenses just long focus. I have heard the performance of the Hektor with 4x5 is very good.

    There were also some early Leitz lenses designed for larger formats (than 35mm). Ole would probably be able to give more details.

    None of the Visoflexes took M mount lenses directly and focused to infinity.
    There are a variety of adapters that go between the lens head and the front of the Viso. The most useful was the focusing adapter #16464 used in addition to a sizing adapter for each lens head(L&dia)

    A few M mount lenses split to fit the Visoflex. I think my Summicron does but I'm a Continent away from it

    Ian,
    The Summicron was too short to focus with the Viso although the head separates for use with something like a "SOOKY"(?) not sure of the # though.
    Gotta love those old catalog numbers!

    For macro work the 50mm Summicron isn't focussed at Infinity

    My Leica books are in the UK but doing a quick search confirms what I remember, Stephen Gandy says of the DR 50mm Summicron "For Visoflex fans, the focusing head of the DR will unscrew for bellows close up work."
