A 2:1 magnification and f/13 aperture on this 28mm probe lens enables extreme close-up detail, with a 360-degree rotating barrel, built-in adjustable LED ring light, and 20cm waterproof front section. The kit's included straight and 90° tubes combined with manual focus and sapphire glass optics offer versatile composition for narrow or angled spaces. This lens suits macro photographers and filmmakers capturing insects, miniature sets, or underwater scenes where direct illumination and 0.3-inch working distances are critical.
