Marc: My experience with the BOOWU-M is that only collapsible Elmars & Summicrons can be used unadapted via the built-in mini-bayonet at the end of the lens tube. Rigid Summicrons can't be de-coupled from the focusing mount and can only be used after the lens head is separated and attached via the UOORF mini-bayonet adapter. Are you saying that the BOOWU-M differs from the BOOWUM in that the latter can accommodate a late model Summicron 50, focus mount and all? I can't imagine this working since resultant displacement (i.e. retaining the rigid focus mount - even locked) will throw off the preset focus. John Barnabas john@ucs.com
