【2x Telephoto Lens Converter】 Designed for smartphones with a built-in 5x telephoto camera, this converter doubles the optical zoom capability, turning a 5x (120mm equivalent) lens into a powerful 10x (240mm equivalent) zoom. It enables distant shooting without digital cropping and image loss. 【200mm/300mm Macro Lenses】 Attach these macro lenses in front of the converter to achieve powerful telephoto macro capabilities with closer focus but less distortion. Use individually for different magnifications (200mm or 300mm), or stack them together for a stronger magnifying effect. 【Compact and Lightweight】 Compared to standard external zoom lenses, this 2x converter is shorter and lighter. It features a 17mm thread for 17mm threaded phone cages, cases, and lens clips. 【Multicoated Optical Glass】 7 elements in 5 groups of HD optical glass and multiple nanocoatings reduce glare and distortion, resist water, fingerprints, and scratches, and ensure excellent light transmission. A cleaning cloth is included.
