Hi all OMers,
I did some more searching and found "Domestic_platapus" on
ebay, seems to have sold an adapter for 7000/9000-O/M not too long back.
The common adapter for the 7000/9000/alpha on ebay seems to be to Minolta MD,
which has a register distance 2.28mm less, than that of an OM. So it would
would need an added spacer of ~2.28mm with an OM flange to make it adapt to
OM? At a wild guess from adapter picture, this would add a total incl 2.2mm
above,of 7mm to the new register of an OM. So maybe a ~14% change in FL.
Sounds a large sacrifice and it might still not accommodate the wide angle
OM's with the protruding lens guard at rear.

Hi Carlos et al,
Sounds like maybe the "Bowen" adapter has to have a weak
glass element, because either the mounting lugs on the flange interfere
and/or because the throat diameters are similar and so are incompatible.
Adding the lens allows the flanges/throats to be separated.
I could not find any bowers alpha-OM adapters listed on ebay, although there
are lots of adapters for other vendor's lenses to alpha. This means you could
kludge an adapter using a weak lens adapter and machining it down and attaching
an OM flange if the bowen adapter is unavailable?.
The pros of doing that would be a 25Mpixel OM lens compatible, FF camera *with
IS *!
You can't get that with any Canon adapted body.
Reading the Alpha reviews it seems like it is pretty capable, although slightly
larger than Canon 5D mkII. Seems like the viewfinder is more OM like with a
large bright prism too.
Given the high resale prices of Canons, maybe Alphas will drop in price
quicker. In two years, you could get a deal on a used alpha 900 to adapt to
your old OM's?

Yes, but with such a small distance, the camera's mount should be quite
_wider_ than the lens' mount, otherwise there would be no room for the
bayonet lugs:

It also mentions incompatibilities with some Zuikos as well :-( Definitely
not a good solution.
