I have a lens (not Zuiko !) which appears to have some separation of a cemented
group, shows some coloured interference fringes. What is likely to be the
effect
of this separation on the resultant images ? As yet I have not had a chance to
test this lens and look at the results and don't have a good example to compare
it
with anyhow.
