John,

I heard about the Mamiya 300 APO. In my circumstance (and Doug?s, I 
imagine), I would like to use the same lens for both my DMR and S (006). 
Having an adapter, which works (with limitations) on the S, is a huge boon, 
as the 180/2 and 280/4 are two of my favourite lenses - virtually 
irreplaceable.

Charlie
