The NEEWER 90 18mm 2X macro lens is designed for mobile video recording with smartphones such as iPhone and Samsung models. This specialized macro lens features a 340 mm slim aluminum tube with an 18 mm focal length, allowing access to deep and narrow spaces while maintaining a safe distance from the subject. With 2x magnification and a 100° field of view, it captures detailed close-ups of miniature models, food, animals, and other small subjects. The lens integrates a front-facing LED ring light with USB Type-C charging for illumination in low-light conditions and offers waterproof performance for underwater photography up to 200 mm depth. Constructed with high-resolution optical glass made of 16 lenses in 12 groups, the lens delivers clear, sharp images. It requires a phone case with a 17 mm threaded connection for mounting. The package includes a versatile support bracket with an Arca-type base and 1/4 inch and 3/8 inch threaded holes for tripod or rail mounting. The aluminum alloy tube ensures durability with rust and scratch resistance. This probe lens is particularly suitable for exploring tight spaces, product detail photography, and creative macro videography applications where standard lenses cannot reach.
