Panasonic 100-300 II purple fringing on Olympus bodies?

I'm looking for a long zoom to be used on an E-M1 II. Part of the driver for the lens is to have a backup for a Canon EOS system on an "expedition" type trip later this year.

I tested a Panasonic 100-300 II and it did pretty well, except for significant purple fringing/CA in some shots.

I'm trying to understand if the specific lens I tested was maybe a dud, or if this model of lens isn't a good match for an Olympus body.

Have people who've used this lens on an Olympus body noticed significant CA?

Have people who've also used the lens on a Panasonic body noticed significant CA?

Has anyone used this lens on an Olympus body, with a 2A or 2E filter on the lens?

The reason for the third question is article below by Alan Watson Forster who identifies several Panasonic lenses (but not the 100-300 II) which exhibit CA on Olympus bodies. He believes the problem is Olympus and Panasonic use different internal UV filters. The fix appears be to use a 2A or 2E on the lens in question.

100% crop, no de-fringing applied.

100% crop, de-fringed as far as possible, but very soft edges.

100% crop from Canon, no de-fringing needed.
