400D with an OM adapter for Zuiko lenses

Hi there,

taking into account that my father has an Olympus OM system (film), I would like to use your lenses on my 400D.

I saw on a web site this adapter:

I'd like to get your opinion on whether it will be a good investment to buy the adapter, even though I know all automatic (autofocos, and aperture) will not work.

From what I read, the camera will calculate exposure.

The lenses are:

• OM 50mm 1.8

• OM 35mm 2.2 (not sure is F point is that)

Thanks in advance,

Best Regards
Nuno
