| The tele converter from Reeflex adds a 600 mm telephoto camera to the iPhone 17 Pro. |
Smartphone photography just got a serious zoom upgrade, but not from Samsung or Apple.
While Chinese giants like Oppo and Vivo have been busy integrating dedicated telephoto converters into their latest flagships—think the Find X9 Ultra and X300 Ultra—Samsung and Apple have stayed conspicuously quiet on that front. Enter Reeflex, a third-party accessory maker that’s decided to fill the gap with a new 300–600mm telephoto converter designed for the Samsung Galaxy S26 Ultra, the iPhone 17 Pro, and the iPhone 17 Pro Max.
But before you get too excited about turning your pocketable phone into a super-telephoto monster, let’s talk about what this lens actually does—and what it doesn’t.
The Promise vs. The Reality
Reeflex’s marketing claims a “300–600mm” focal range, which sounds incredible. However, the fine print tells a different story. The lens itself provides a 300mm equivalent focal length when attached to the periscope telephoto camera on your iPhone or Samsung flagship. That’s still a massive leap from the iPhone’s native 100mm telephoto, but the advertised 600mm is only achievable via digital zoom – and that comes with a heavy price.
When you push to 600mm, the resolution drops from 48 megapixels down to just 12 megapixels. So you’re trading detail for reach. Is it worth it? For birdwatchers, sports fans, or anyone who regularly shoots distant subjects, 300mm optical might already be a game-changer. But the 600mm claim is, at best, optimistic.
“Even 300mm is a huge step up from the 100mm that iPhone users are used to,” notes one early reviewer. “Just don’t expect miracles at the long end.”
What’s in the Box? Specs You Should Know
The Reeflex Ultra Tele-Converter isn’t a tiny clip-on lens. It’s a serious piece of glass packed into a metal housing that measures:
- Length: 7 cm (2.75 inches)
- Diameter: 5.5 cm (2.16 inches)
- Weight: 308 grams (10.8 ounces)
That’s heavier than an iPhone 17 Pro itself, so you’ll definitely feel it in your bag. The minimum focus distance is 6.8 meters (about 22 feet), meaning you can’t use this for macro shots or close-up details. This is purely for long-distance work.
One nice touch: the front of the lens is magnetic, so you can attach proprietary ND, polarizing, or UV filters. Just keep in mind those are sold separately.
How to Attach It – And What You’ll Need
Reeflex includes a protective case designed specifically for the iPhone 17 Pro, iPhone 17 Pro Max, and Samsung Galaxy S26 Ultra models. The lens mounts onto that case, so if you’re using a different phone or a third-party case, you’re out of luck.
This approach isn’t new—similar lens systems from Moment and ShiftCam have used case-based mounting for years. But Reeflex’s focus on only the latest Pro iPhones and Galaxy Ultra models means users of older devices (or non-Ultra Samsungs) are left in the cold.
Pricing: Kickstarter Deal vs. Retail
The Reeflex Ultra Tele-Converter is currently crowdfunding on Kickstarter, and early birds can grab it at a significant discount.
👉 Check out the Reeflex Kickstarter campaign here for the latest pledge options and delivery estimates.
- Super Early Bird price: $280
- Expected retail price: $445
That’s a solid saving if you’re willing to back a crowdfunding campaign. However, keep in mind that shipping costs, import sales tax, and customs duties are not included in the pledge price, and Reeflex ships worldwide.
Why This Matters (And Where Samsung and Apple Are Falling Behind)
Oppo and Vivo have been quietly integrating telephoto converters into their own flagship phones—the Find X9 Ultra and X300 Ultra come with bespoke lens attachments that work seamlessly with the built-in periscope cameras. Samsung and Apple, meanwhile, have focused on internal zoom improvements but haven’t offered first-party external telephoto solutions.
That leaves a gap that third-party manufacturers like Reeflex are happy to fill. But it’s worth asking: why should you have to buy a 1,300 phone?
The iPhone 17 Pro starts at $1,099 on Amazon, and the Galaxy S26 Ultra isn’t much cheaper. For that kind of money, some users expect better native telephoto capabilities. Then again, physics is physics – fitting a true 300mm optical zoom into a slim smartphone body is virtually impossible. So external lenses like this one may be the only realistic path forward for extreme zoom on non-Chinese flagships.
Who Is This Lens For?
Let’s be honest: this is not for casual photographers. The 308g weight, the bulky size, the 6.8m minimum focus distance, and the need to carry a special case make it a niche tool. But if you’re any of the following, the Reeflex Ultra Tele-Converter could be exactly what you’ve been waiting for:
- Wildlife enthusiasts who want to shoot birds or animals without carrying a full DSLR kit
- Sports fans capturing action from stadium seats
- Travel photographers who want reach without checking a bag
- Content creators who need unique, compressed telephoto perspectives
For everyone else? The 5x optical zoom already on the iPhone 17 Pro (120mm equivalent) or the 10x zoom on the Galaxy S26 Ultra will probably be more than enough.
Final Verdict: A Promising But Flawed Powerhouse
Reeflex has done something genuinely impressive: created a compact, 300mm optical telephoto lens that attaches to a smartphone. The build quality looks solid, the magnetic filter mount is a smart addition, and the Kickstarter price is reasonable for what you’re getting.
But the 600mm claim leaves a bad taste, and the weight and size mean this isn’t something you’ll carry every day. Also, remember that you’re backing a crowdfunding campaign – production delays and quality control issues are always a risk.
If you’re a dedicated smartphone photographer who absolutely needs that extra reach, the Reeflex Ultra Tele-Converter is worth a serious look. Just go in with your eyes open about the limitations.
Bottom line: Great for specialists. Overkill for everyone else.
