On February 26, 2026, SANDMARC, an American accessory manufacturer, unveiled the Tetraprism 72mm Telephoto Extender for iPhone. This innovative lens boosts the zoom capability by threefold. With a focal length of 72mm, it weighs a mere 180g, stands 70mm tall, and boasts a diameter of 40.5mm. Equipped with a built-in 17mm threaded interface, it is tailor-made for the iPhone's tetra-prism telephoto system. This design enables the iPhone 17 Pro series to achieve an impressive 24x zoom, while also providing older iPhone models with a 15x hybrid zoom capability.
Crafted from multi-element, multi-coated glass, the lens effectively minimizes glare and ensures precise color reproduction. This maintains exceptional image quality for long-distance shots and tackles the common problem of detail degradation at high digital zoom levels.
The product's modular design allows for direct mounting on iPhone-specific lens cases. Additionally, it is compatible with SANDMARC's filters and a range of photography accessories, making it an excellent choice for wildlife photography, event documentation, and capturing distant landscapes.
