many companies serve specialized markets. It's interesting that a photography and electronics giant like Sony does choose to serve several very high end and
A F65 (or other Fs) isn't necesarly the queen in the niche market you mentionned. In fact it is not at all. The Aaton and similar beasts rule the very high-end motion production, not the still photography crowd shooting a bunch of rather low budget commercials. Sony might be a component provider for them. If my memory's correct, Aaton sensor is provided by Dalsa. It's french tech, DNG raw and proxies in DNxHD, they work very well in Hollywood, small company, same as Angénieux, small company located in the middle of a red-neck area in France. They do good stuff and they sell ww. Or Cooke lenses. The list is long.
I'm thinking of Grass Valley for example, wich is in fact a small company compared to Sony or Panasonic, they inundated the ww market with their 100.000 euros Elite cameras. There are more Grass Valley thomson bodies here in Teevees than all the sony and Panasonic together, because that's what want the high-end users for serious live coverage. The cost of those systems are out of range for a still imagery based production. Grass Valley makes profit, and they aren't Sony giant, but they make the profits within a very limited but very demanding niche market, same as Aaton. Sony is into this market but isn't ruling it, in fact they are more active and interested in the middle and low-end productions (not talking about low-end in terms of artistical value here but in terms of budget) because for a company like Sony they focus where the max profits are but in the very high-end the marketplace is much more fragmentated a a truth space exists for small companies.
The Cuantel Pablo's facilities are closing and how streange (how strange really) that a year ago, you had to put 15.000 bucks on the table to get a Smoke license, and suddenly, as by magic, the 2013 version, more powerfull, is sold at less than 4.000. What were those 11.000 then? Those 11.000 were because they could, now they can't anymore.
If a small company gives the tools the pros want, pros will continue to buy them. Grass Valley survives and makes profit selling cameras much more expensive than Sony, because there is a market that want thoses cameras, and in general (no, in general no, in absolute) those are highly trained and skilled operators who work where the real money is but not where the real profits are for a big company. I'm sure there will always be a market different than the standardized mass productions as soon as they know how to spot their user needs, and within this market, price is not an issue.
Analogicaly, one can say, and would be right, that there are some japanese cars technologically more advanced, powerfull, cheaper and faster than Ferraris, so why buying Ferrari then? The thing is that Ferrari buyers want to drive a Ferrari, not a plastic electronic asiatic car that sounds like a vacuum cleaner, and they are ready to pay what Ferrari is asking them for having this experience. It's as simple.
