Currently, there isn't even a widely available commercial adapter to use OM AF/PF lenses manually. These rare lenses (which only fit two and a half mediocre-featured film camera models) have a mechanical aperture control but no aperture ring on the lens, and they are so obscure that no one yet marketed even a NEX bayonet adapter (which you can readily buy for lenses as obscure as Pentax 110 or 1960's Kodak bayonet) with the aperture slider you would need for OM AF.
These won't even fit on all OM adapters due to extra coupling elements.
Some of these can be manually focused by simply pulling and pushing on the front part, there will still be no aperture control (which would be nigh impossible to implement in a glassless adapter for EOS - there needs to be a motor in the adapter!) unless you are willing to hack the lens and unmount it to change aperture.
