Close focusing refers to a camera lens's ability to focus on subjects that are very near to the camera. Most standard lenses allow a minimum focus distance of around 20 cm, while lenses or cameras with advanced close-focusing capabilities often feature a "macro mode" for even shorter distances. Close focusing is essential for capturing detailed images of small subjects, textures, or intricate patterns, making it especially useful in macro, nature, and product photography. Photographers use close focusing to highlight fine details and create striking, high-impact images.
