I don't think it is "dare" or "dare not" answer.
I think they do not sure at the moment, given the changes Olympus is going thru.
It could be Vietnam, China or Japan (when they cannot find a Outsource partner that can pass all the QC).
Personally (and I asked a few photographer friends as well), I don't think it matters, as long as JIP can
provides the same reliability as the previous Olympus Pro Lens. If the outsourced manufacturer fails JIP,
JIP can always find another manufacturer and offer a replacement for the faulty item.
After all, Apple has replaced my Airpods after 3 months (FOC) and Samsung has replaced my brother's
Galaxy Note Mobile & Battery even after the warranty period when their manufacturing partner screw them up

Ask 1 simple question that they dare NOT answer, so far, which is very strange. [ Where is this lens made? ]
Even a SGD$200 lens states clearly where they make it.
Some fans rush to defend not telling or to deflect from the question - and attack the person asking.
It is sad.
This is a SGD$10,000 lens.
The lens could very well be made in Japan.
Or in China.
Or in Vietnam.
Or Malaysia.
Or Taiwan.
Or Thailand.
Or other country.
Not unreasonable to ask the manufacturer to say so firmly.
