Get up to 24x optical zoom on the iPhone 17 Pro using an innovative lens accessory that elevates your mobile photography game.
Zoom Beyond Limits: The Quest for 24x on iPhone 17 Pro
Ever wished your iPhone 17 Pro could zoom in deeper without losing image quality? While Apple hasn’t slipped a 24x zoom camera into the latest model, there’s a clever workaround that might just blow your mind. Enter the Sandmarc Tetraprism 72mm lens—a game-changing clip-on accessory designed to extend your iPhone’s telephoto capabilities dramatically.

This lens is a revelation for tech enthusiasts and photography lovers alike, promising DSLR-level zoom performance without the bulk of a full camera setup.
Meet the Sandmarc Tetraprism 72mm Lens: Your iPhone’s New Best Friend
Sandmarc, a company known for enhancing mobile photography gear, recently launched the $299 Tetraprism 72mm Lens. This isn’t just another digital zoom trick—it’s a bona fide optical lens crafted to clip onto your iPhone and amplify its built-in telephoto system.
When you pair this lens with the iPhone 17 Pro or the iPhone 17 Pro Max, it unlocks up to 24x zoom. How? The lens adds a 3x optical magnification that works in tandem with your phone’s native tetraprism zoom. Unlike digital zoom, which simply crops and enlarges photos (often leading to pixelated images), this optical boost magnifies the scene before the light even hits the sensor. The result? Sharper shots with much better detail retention.
“You get improved subject separation, stronger background compression, and better detail retention at longer distances,” says Sandmarc, highlighting the lens’s advantage for wildlife, cityscapes, and live events photography.
Craftsmanship that Keeps Your Shots True
The 72mm lens isn’t just powerful—it’s also meticulously designed. Constructed from multi-element, multi-coated glass, it maintains color accuracy and reduces flare, ensuring your photos look natural and vibrant.
Weighing in at 180 grams, the lens mounts securely over the iPhone’s tetraprism telephoto lens using Sandmarc’s dedicated case and filter mount system. This modular setup means you can easily swap lenses or add filters, turning your iPhone into a versatile photography powerhouse.

Compatibility Beyond the Latest iPhone
While the headline grabber is the 24x zoom on the iPhone 17 Pro range, this lens isn’t just for the newest models. It also works with previous generations, delivering up to 15x zoom on the iPhone 16 Pro, iPhone 16 Pro Max, and iPhone 15 Pro Max. This kind of backward compatibility makes it an enticing option for anyone looking to upgrade their phone photography without immediately splurging on the latest handset.
A Modular Lens System for the Road
The Tetraprism 72mm Lens measures 70mm tall with a 40.5mm diameter and features a 17mm inner thread for attaching filters. It’s part of Sandmarc’s larger ecosystem designed for travel and adventure photographers who want a lightweight, adaptable kit.
Watch it in action:
It’s not just a lens; it’s a photography upgrade that fits right in your pocket, making it easier than ever to capture faraway subjects with clarity and style.
Why Optical Zoom Still Rules
In the age of AI and digital enhancements, optical zoom remains the gold standard, especially for mobile devices. The Tetraprism lens adds genuine magnification instead of cropping pixels, which means your shots retain fine details, have less noise, and show richer depth.
Whether you’re capturing a bird perched on a distant tree branch, the skyline of a bustling city, or the expressions of performers at a concert, this lens gives your iPhone a serious boost.
Final Thoughts: The iPhone Zoom Upgrade You Didn’t Know You Needed
So, no, Apple didn’t sneak a 24x zoom camera into the iPhone 17 Pro. But with the Sandmarc Tetraprism 72mm Lens, you can approximate that DSLR-style telephoto reach right from your smartphone. It’s modular, precise, and built to enhance your mobile photography without the hassle of carrying extra gear.
If you love pushing your phone’s camera to its limits, this lens might just be the accessory you didn’t know you were waiting for.
