Good question - I simply do not know anymore. A lot of the major camera brands used to have a full service depots here in Canada, but some them have been shutting down, or in other cases, certain lines of products are no longer repairable due to lack or parts.
Not just cameras either, but mechanical watches & mechanical clocks, TVs and other electronics, heck, and so forth all seem to have no parts or in some cases, no places left you can get any repairs. We seem to live in a throw away society.
Heck, just a couple months ago I tried to find some replacement blades for an older commercial quality food processor my wife has, only to find out that there is only *one*
place in all of North America (that's Canada, USA and Mexico folks) that has replacement parts. Yet, the unit works great, better than new ones - but there you go.
