Martin Gallego published what appears to be the first test of the “older” Four Thirds lenses on the new OM-1:
Some of the old Pro FT lenses are technological gems that may never be re-manufactured. Users who still own them may feel lucky. You should know that they go very well with the OM System / Olympus OM-1 and they can still give us a lot of satisfaction.
