Well, I didn't mean that Canon products are particularly bad in quality.

I own a perfectly functioning 40D from 2007 myself, which I replaced by a Sony A7III just recently, as I hate the fact, that Canon tries to force their customers to buy their own expensive RF lenses.

Of course cameras are impressive pieces of technology. Still I understand the sentiment of the above commenter. My last comment was an overstatement, still there is a substantial chance of a hardware failure.

And Sony forces you to buy their own expensive E-Mount lenses?

To be honest, Canon EF mount lenses are probably the best buy if you are looking for compatibility: there's adapters for Sony E-Mount, Canon RF-mount, etc.

The reason RF, Z, and E mount exist is because you can make the camera body much slimmer in MILC.

It's much easier building adapters for lenses going from DSLR -> MILC. It might not be possible to go the other way around.

Sony has opened up the mount specification to third party lens manufacturers, Canon didn't.

As a result, there is a wide range of third party lenses evailable for Sony FE, none for Canon RF.

My 20D from 2004 is still fully-functional, as is my Elan IIe from 1995.

FWIW, glass holds it's value well in the used market.

Just buying some old Canon FD mount stuff off of eBay lately. You aren't kidding! That vintage glass really has some beautiful character, it's worth shooting all manual to me.
