Hyperfocal distance isn't just about sharpness, it's about locking in a range where everything from a certain point to infinity is acceptably sharp. When xena_fox39 mentioned calculations on the lens barrel, it reminded me how vintage lenses often have those markings, but modern ones lack them, so you have to use apps or charts. Once you dial in that distance, you can shoot without even looking through the viewfinder, which is perfect for street photography where timing is everything. The key is to practice in different lighting conditions since depth of field changes with aperture, and that affects your hyperfocal point. It turns your camera into a tool that reacts faster than autofocus, keeping the scene natural because you're not fiddling with settings.
