Camera tech has improved by such a crazy amount in 10 years I can't even imagine what it'll look like in 2025. Like damn.
Isn't that kinda weird though.
I thought it was all just glass.
I would say it's mostly been to rapidly falling prices. DSLR's didn't even really start catching on until 2005 (they were around before that but extremely cost-prohibitive.) Now? I could get a good DSLR (which has way more functions and options than anything released in 2005) for like $500. The high end of DSLR gear currently consists of stuff that would have fetched a small fortune ten years ago for the same quality. A 2005 lens might be compatible, but even lenses have developed a fair bit. In addition there's other innovations, like in-body stabilization, and mirrorless cameras have started to catch on (I've read a couple "death of DSLR" articles.)
Like most tech, it's always "existed" but the higher end keeps dropping in price and size until it's attainable for most people.
Did you know you can get a 4K DSLR for $1500? This is something an indie film maker could easily use to make an entire feature film, and 4K (digital) films didn't even exist a decade ago! If you wanted to make a feature back then, you needed to use film and I shouldn't even need to say how incredibly expensive that could get. (Let's say, a lot more than $1500 for potentially not as high quality footage.)
Now it seems most stuff is being made in 6K digital with RED cameras and the like. In a whole 10 years, you'll probably be able to get a camera that offers the same picture quality but for $1500 instead of $20,000. (And the high end will have something even better to replace it, like 16K or something insane like that.)
