You too can sell stuff for $100k. Just make something useful to someone who can throw around $100k.
You think a $100K lens is crazy? Wait until you hear what people are paying for enterprise software.
Modern studio pictures that get nominated for best picture or best cinematography cost around $80 million on average. If you look at highest grossing films the budgets are closer to $175 million on average – even taking into account the $20 million budget of Demon Slayer: Infinity Castle.
Isn't it more that when you're spending that kind of money that $100k for the "best" thing becomes kind of like "insurance" where you don't want to be the one who doesn't use "the best" when "the best" costs about 0.1% of the picture's budget?
Additionally a studio can buy the $100,000 lens once and use it on many films. But it's not like you can reuse Fable 5.2 in the same way.
Furthermore, you make one lense and rent it out, apparently some Panavision lenses made in 60’s are still in use. It doesn’t churn constantly electricity and GPU-chips sucking in more and more resources like these things do.and at the same time, it is quite hard to find the exact cases where the markup is justified, unlike with those lenses. Maybe in cybersecurity etc. but even there some Chinese model can be almost equally good or even better.
Those lenses save money in budgets and make money in getting people into theatre or streaming services to watch films creating profits way beyond their cost. I think in terms of economics that is productivity increase justifying the cost. We are still waiting for that productivity increase come from the AI industry.
