You have two different families of reflex housings -- The original PLOOT and its successor, the Visofliex (later, the Viso I). These are fascinating items but are more today for those wishing to learn how photographers operated in, say, 1949, than for practical use. The Viso III only came in M BM. The Visoflex II and IIa, both of which were produced in LTM versions. The IIa is rather rare but the II is the most common of teh Visoflex variants. The Leitz catalogue code is OUCLO/16458 (Viso II LTM with 90-degree viewfinder), or OTYDO/16457 (LTM VIso II housing alone) and OTXBO/16460 (90-degree VF alone). The adapters needed depend on the reflex housing used, but let us presume that you are going with a II: 4.5/13.5cm Hektor lens head (remove the head from the lens tube) OTZFO/16464 Universal Focusing Mount with OTSRO/16472 lens tube. Both of these are readily available. 4/9cm Elmar lens head (again, remove the lens head from the lens tube -- this will not work for the late three-element Elmar, I believe) OUAGO/16467 You could also use a Bellows II rig with the supplied 16558 adapter for the 9cm Elmar lens head., or with UOOVH/16580 for the Hektor lens head. I haven't a clue about the Canon, not being familiar with that lens, but I doubt that you'd be able to maintain infinity focus with it. These are not especially long lenses. Many of us using Viso rigs work with the 200/280/400 Telyts. Marc msmall at aya.yale.edu Cha robh b?s fir gun ghr?s fir!
