I read an interesting article about COVID-19 and its impact on the supply chain in many industries.
Key point -- for the last forty years or so, manufacturing has followed the "just in time" philosophy of keeping minimal inventory of raw materials and components on hand and relied on quick shipments from suppliers. That's now coming back to bite manufacturers in the butt. The article gave several examples where companies cannot get simple things (one example was a tent manufacturer who couldn't get Velcro and thus their entire manufacturing line was disrupted.)
Complicating this is that most manufacturers no longer have warehousing space because they relied on shippers to get their components to them as they were needed. Now, companies are having to not only interrupt their manufacturing lines while they wait for parts, but they don't have any warehouse space to store the parts they can get (and of course they are now ordering more parts than what they need immediately, because they are uncertain if the parts will be available in the future). Warehouse space can't be added overnight and companies are in bidding wars to secure pre-existing space.
We've read about things like chip shortages, but we never think about all the other components that go into cameras and lenses that can hold things up, something as simple as securing the right screws to assemble a lens, rubber gaskets for weather sealing, Styrofoam pellets needed to make packaging etc. etc.
