iPhone 17 Pro Gets 24x Zoom With Sandmarc’s New Tetraprism Lens

California-based accessories maker Sandmarc has introduced a new Tetraprism 72mm Lens for iPhone that adds 3x magnification over the iPhone 17 Pro’s built-in tetraprism telephoto camera.

iPhone 17 Pro’s 48 MP Fusion Telephoto offers true 4× optical zoom with a focal length equivalent to 100mm. When combined with the Sandmarc 72mm lens, which adds true optical magnification, it can extend the effective zoom up to 24x on the iPhone 17 Pro and iPhone 17 Pro Max. According to Sandmarc, users get 12x zoom at full 48MP resolution, or up to 24x at 24MP.

Sandmarc says the multi-element, multi-colored glass construction maintains sharpness and color accuracy while reducing glare. The company also says the visual compression effect is perfect for landscapes, cityscapes, and wildlife, or the kind of strong, layered looks you’d normally need a dedicated camera to achieve.

The 72mm lens sits next to Sandmarc’s existing 48mm model, offering 2x magnification. Both mount directly to the tetraprism camera, but require a third-party camera app like Halide or Blackmagic Camera, as the stock Apple Camera app can automatically change lenses.

The lens is also compatible with the iPhone 16 Pro, iPhone 16 Pro Max, and iPhone 15 Pro Max, with 15x zoom access on those models. The lens itself weighs 180 grams and includes a Sandmarc case and filter mounting system. The 72mm lens costs $299, while the 48mm model is priced at $249. Both can be ordered from the Sandmarc website.
