You can still get parts and repair for the old cars because they are worth fixing. You can get your 40-50 years old cameras repaired also because they are worth fixing. You can't get parts or repair for a less than 10 year old camera like the T2i because you can buy good working used one cheap and it's not that much expensive for the new version. So these cameras are not worth fixing.
No, it is not entirely a matter of economics: fix vs. total. Nor do digital cameras autoamtically
become obsolete. That used to be true, but it may not be in the future. Just as with cars, there
are good ones that people want to keep. In the future --as cameras get more and more complex--
that will become more and more true.
New cameras contain ASICs, microrprocessors and memory chips: all of them unsocketed!
And electronics packaging and mounting technology has changed: much larger ICs, surface mount,
multi-layer boards. Such boards are nearly impossible to fix.
Such technology can be maintainable, but it has to built for maintainability: modularity, self-tests,
robust connectors and everything documented in a Service Manual.
It's harder to fix a modern digital camera than the Aegis Combat System on a US Navy guided missle
crusier--because the later is all rack-mount and modular. The tech swaps out boards until the radar
(or whatever) starts working again. Every interface beween Aegis modules is documented.
It's all meant to be maintained indefinitely.
Some mechanical cameras were easy to work on, some were very difficult to work on.
It was possible to build them either way. It still is with digital cameras.
If the public comes to accept disposable cars with the hood welded shut, that is what
Ford and GM will sell. Fortunately, consumers realize that a car is an investment
worth protecting.
But Uncle Bob will spend $6000 on a camera that he has to throw away when it quits
working in just 37 months. Bob has money to burn!
