Focus is more than just FOCUS! Think of it as a mental focus. What are you focusing on in the scene? That is what you want to take a photograph of. So, you have a lot of options to make that happen. Maybe it is zoom, cropping, lighting, composition, or maybe it is shutter speed. And not one of those options I mentioned was actually turning the focus ring on your lens. Yes, you need to focus on your camera. But oftentimes, your "focus" needs to be coming from something 0ther than your focus ring alone.
