Also, I don't think Apple (as of today) has the capability to "obliterate" the pro market. Are you simply talking about buying other companies, or making new home-grown products?
But it goes well beyond that. Apple has been investing for decades into video editing and post production software, codecs, image processing, AI, and electronics manufacturing. Plus, it's a brand already trusted by the video and photography industry which has been using their hardware and software products for decades.
They could indeed buy other companies, but I was referring to creating new products.
With respect to CMOS chips you can go from from calling up Sony and ordering one off the menu with your custom requirements, to designing the NAND/pixel interconnects, microlenses, downstream dual-gain architectures, to working on the bonding chemistry, masked pixels, CFAs etc, etc. However, all this stuff is patented up the wazoo, and companies like Sony, Samsung, Aptina, OmniVision etc do not simply hand-over world-class tech like this.
Apple is very good at supply chain logistics, overall packaging and design, UX, Software, etc. However, I don't see them challenging the established players on core technology.
