There’s nothing worse than having an issue with your camera only to contact the manufacturer and find that they can’t repair it. It’s a lot more common an issue than it used to be, purely because of the number of older and used bodies out there still being put to regular use. I’ve still got DSLRs here that are at least a decade old but also fantastic for timelapse, so they get used. But what if they die?
Most manufacturers don’t announce when a product is reaching end of life and support is going away. Canon, however, does. The good news is that your shiny new EOS R bodies have a good amount of life left in them. They’re even supporting the original EOS R until 2029. The bad news, however, is that most of your DSLRs and some EOS M mirrorless cameras won’t get support for much longer.
