Would you say I can judge if the focusing mechanism is damaged by checking whether the lens can autofocus or not (by which I mean, notify me it achieved focus through focus confirmation light and beeping)? Or do I have to evaluate the sharpness of the pictures?

If it's broken, it will not focus at all, no AF, no manual focus. You'll turn the focus ring and nothing will happen. It's not subtle at all.

I've broken two of them.
