Hyperfocal distance is the closest distance at which a lens can be focused while keeping objects at infinity acceptably sharp. When a lens is focused at this distance, everything from half the hyperfocal distance to infinity appears in sharp focus, making it an essential concept in landscape, architectural, and street photography.
Mastering hyperfocal distance allows photographers to maximise depth of field and ensure that both foreground and background elements remain sharp. It is particularly useful when shooting with small apertures and wide-angle lenses, helping create images with clarity and detail throughout the scene.
