Hooray,
Found one in OM mount in Osaka after pinging a yabe dealer--a 4 month search. It has the odd aperture asymmetry issue which seems to plague a substantial minority of the CV series.
At least I can keep the number of adapters to a minimum. I wonder if its bokeh is nicer
than the Tam sp 180/2.8 which has the same MFD but is internal focusing--I have read that that results in edgier bokeh on average. This is going to be a great travel lens.
Sometimes I think I have a nutty obsession. It is APO, 49mm filter, nice bokeh, goes 1:4.
Seems reasonable.
