Originally posted by Gimbal No, that is a bug.
If the camera suddenly restarts then something has happened that the camera couldn't handle. The restart is part of the design so in that sense the watchdog function worked as designed but the fact that it had to act to regain control over the camera is a failure. It is not a nice a behavior.
But being such a constructed problem I don't care at all.
If it worked as intended (for an extreme case), that's not a bug. You may think it should handle it differently, but it is not a bug. A bug being by definition the camera failing to do what the intended behavior (by the developers) was, or doing something else. In any case, whether it was intentional or not, it seems like sensible behavior (runaway motor, shut it down). That's handling the problem. Saying it should never shutdown, never restart, no matter whatever dumb thing you do to it seems extreme. Of course I'm assuming that if in truth it does have a shutdown timer or overheating sensor or whatever that the scenarios they are trying to protect against are the failure of one system in the camera from frying the whole thing or having it burst into flames. (For instance if a faulty switch caused the AF motor to go crazy without user interaction.)
But if someone is going to purposely do potentially damaging things to it and even if it then just breaks, the bug is in the user behavior, not the camera...
