The most common reason for a company to drop support for repairing older electronic gear is the fact that one or more electronic components on the circuit boards are no longer being produced by a THIRD party.
Another (somewhat related) reason is that it's often cheaper to buy a replacement (or even a newer model) on the used market than to have an old camera repaired. If you decide to go that route, there are some caveats:
- The 50D lacks an infrared receiver and can therefore not be used with an IR trigger. (But it's otherwise a much better camera than the 40D.)
- The 60D (uniquely in the n0D product line) lacks autofocus microadjustment.
- The 70D is prone to a component failure on the main circuit board, which renders the camera inoperable and is expensive to repair. (However, Canon has recently been known to do the repair for free.)
The current model, the 80D, has none of those faults and should be readily available on the used market. You may even find it in the Canon online store as a warranteed refurb.
