DxO One review


Is iPhone is your camera of choice? Then the DxO One will elevate your photography.

1-inch, 20MP sensor ; 32-mm equivalent, f/1.8 lens ; Lightning and Wi-Fi connections ; SuperRAW and RAW uncompressed files ; Great software, UI

High price for a niche camera ; Not for fast action ; No support for Android phones

Although we love the concept, software, convenience, and results of the DxO One, it is expensive. It is also restricted to iOS only, at least for now. For the same price, you can get the original RX100 with a 3x Zeiss optical zoom lens and even greater...

DxO One


The DxO One is an innovative add-on camera for iPhones, designed to boost the quality of the shots you take with your device, but it's plagued by too many issues to recommend.

Very small. 1-inch image sensor. Wide aperture f/1.8 lens. Sharp images. Innovative concept.

Overheats. Short battery life. SuperRAW processing requires a lot of CPU time. Questionable connection design. Inconsistent focus speed. Expensive. Only compatible with iOS devices.

Conclusions The DxO One is another in a line of cameras that has promised to revolutionize smartphone photography. But it's got too many problems for a product that's being sold to consumers, especially at its $600 price point. Overheating and battery...

DxO One review


Sony invented the phone-connected-camera category with its lens-style QX series of lens cameras , followed this year by Olympus' similarly designed Air A01 . Those rely on Wi-Fi to connect to a phone or tablet , and essentially perform wireless...

The DxO One's notable strengths include a well thought-out and attractive design and excellent photo quality on-par with its class.

It's expensive, and it's a little slow with short battery life.

It's a good camera and unquestionably better than that of any iPhone, but the DxO One isn't no-brainer-better than other options for the money. Yet.

DxO ONE Review


Renowned imaging software maker DxO Labs have taken a giant leap from the world of software into the world of hardware with the announcement of the DxO One. Yes, the makers of DxO OpticsPro and the famous DxOMark image quality testing system have...

Being such a small device, it's no wonder there's hardly any external controls. However, on the "top" deck of the camera, as I'm calling it, the One does have a large, two-stage shutter release button. Like a typical camera, a half-press will autofocus...

DxO One Camera Review: iPhone Photo Perfection


No matter how good it is, every third-party iPhone lens faces the same reality: It just doesn't take images as good as the ones from a real camera. The DxO One is the perfect compromise for people who want to get better pictures but don't want to be...

Compact and portable ; Great images for the size ; Full manual controls ; Can use without phone

Expensive ; No lens hood ; Somewhat flimsy connector

Not much larger than a Zippo lighter, the DxO One camera accessory for the iPhone takes tremendous pictures for its size.

DxO One review: A better camera for your iPhone


I've had a chance to shoot with the DxO One iPhone camera for a month, and it's darned impressive—a bit funky (technologically speaking), but darned impressive. As a picture-taking tool, the DxO One is much better than the camera in any iPhone, and you...

Every camera is a package of compromises. But the compromises baked into the DxO One make sense and serve the goal of producing a better camera for your iPhone. DxO offers a 30-day return guarantee so you can buy with minimal risk. It may be overkill...

DxO One Review: Souping Up Your iPhone's Camera Comes at a Cost


How do you combine the ease and connectivity of a smartphone with the quality and control of a camera? It's basically one of the greatest conundrums of our time. Does DxO have the answer? It wants to transform your iPhone 6 into a full-fledged camera...

DxO One review: The iPhone add-on camera's highs and lows


The DxO One is an interesting camera concept, one designed specifically as an add-on for iPhones with the Lightning connector port. The idea is simple: the One delivers the same 1-inch sensor size as found in the Sony RX100 MkIII high-end compact ,...

Great image quality from the 1-inch sensor (same as Sony RX100 MkIII), it's a full-on camera you can fit into your pocket, easy Lightning port connectivity, doesn't drain iPhone battery

Expensive, focus point position sometimes over-ridden, some software bugs/crashes, independent battery (can't draw from iPhone), iOS only, shutter button position not great with iPhone 6 Plus, fussy to stow Lightning connector

DxO One review


DxO puts its optics design and image correction knowhow into a 20Mp camera for your iPhone

High quality sensor ; Easy connectivity ; Excellent iPhone integration

Care needed to avoid covering the lens ; Poor battery life ; Slow access from a locked iPhone

If you want an iPhone accessory to help you take better images, this is a good option, provided you don't mind the extra bit of fiddling about to access the app compared to the quick route to the iPhone camera from a locked screen. However, despite the...

DXO One review - is it better than your iPhone's camera?


A clever idea, but the DXO One is expensive, fiddly to use with an iPhone and I found myself leaving it behind

The acid test for a product like this is how much you use it. During my time with the DXO One, I found it more of a chore than a pleasure to use. It’s simply too fiddly to use conveniently, the iPhone typically produces better-exposed images with more...
