Small ; Good image quality ; Solid app

Exposure often needs a tweak ; Fiddly to use ; Unimpressive AF and shooting performance

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...

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...

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...

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

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.

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...
