Don't worry about that part. This is just a standard disclaimer.That last gray area about "End of Production" is disturbing. Could be they made X amount and that's it, and will let JIP sort out who gets them. Maybe Sigma will make something similar.
And given the fact that we are talking about a $7500 lens for a niche manufacturer, it should be obvious that this is a "build to order"-product. JIP will also not not even start manufacturing these before they have received a large enough patch of confirmed orders to justify ramping up production line.
Oh, and since someone already reminded that these are hand-made one by one, this is only true for final assembly and testing. We are not talking about a one-off product like Hubble here. This is still a mass manufactured consumer product, albeit a very, very low volume one.
Components like lenses, housing and (electro)mechanical parts are not cast/molded and milled/ground manually one at a time. They are made in patches which must be large enough to be profitable and of course the estimated lifetime sale volume must justify launching the whole product in the first place.
On the other hand, if we assume that at least one patch is ever made, better be in that because the next patch may have to wait till kingdom come. I'm pretty sure that Olympus designed this lens as a flagship that was going to increase Olympus brand value á la Bugatti for VW.
Remember that VW makes a loss of $6,25M with every Bugatti they sell but this is exactly how they planned it. They will cover these losses with increased profit from increased sale of lesser premium cars which are made at profit. Or that was the plan anyway.
