They said "strong focus" which implies there is a spectrum of focus and that everything falls on that spectrum of focus. I disagree that any amount of focus precludes any focus on something else, especially in this context.

On second thought, a camera can only focus on one field. So it would make sense if our language only allowed one focus. But what if we had multiple cameras? Or multiple teams or engineers designing a bridge?

Have we gone too far? lol
