DxO One IPhone

Its lab tests are often cited by manufacturers when they tout image quality.  The DxO One IPhone is the company’s first hardware product, which makes it all the more impressive.

It simply uses your phone for control, framing, and sharing. Images can be saved either to your phone or to a MicroSD card in the DxO One . To state the obvious, the DxO One will not work with non-iOS devices due to the Lightning connector requirement.

Despite its petite frame, the DxO one packs a punch on the inside. A 1-inch, 20.2-megapixel sensor records images with significantly more detail than the iPhone’s built-in camera. This is the same sensor format that is popular in advanced compact cameras like the Sony RX100 series. Being based on an older version of the tech, the DxO One is limited to 1080p video at 30 frames per second, compared to the 4K video offered in the latest Sony RX100 V.

The DxO One app allows full manual control over exposure settings for those who want it, but also offers a simple point-and-shoot automatic mode. The camera can even shoot in RAW and, thanks to another recent firmware update, RAW fi

There are only two physical controls on the camera itself. First, there’s the lens cover, which slides down to reveal the lens and turn the device on. Press it all the way down to open the Lightning connector; the lens cover will then spring back into the on position. Other than that, there is a shutter button on the top of the camera that works just like that of any standalone camera. It doesn’t get any simpler than that.

The DxO One has the best software and user interface of any connected camera we’ve reviewed, a very pleasant surprise for the first piece of hardware produced by the company. Even the first version of the app was elegant and simple, and it’s only gotten better. We wish every camera maker would study this device and then try to emulate DxO’s user experience.

One of the great things about the DxO One is its small size. You can easily carry the DxO One in your pocket, connect it to your phone when needed, fire up the app, and grab 20.2MP. The app launches very quickly and the live preview basically loads instantly, which means working with the DxO One really isn’t any slower than working with the iPhone’s native camera and app.

If you’ve ever shot a Sony RX100 or other advanced point-and-shoot with a 1-inch sensor, then you know just how good the image quality is. It is no different from the DxO One. Colors are vibrant, detail is rich, and dynamic range is greatly improved over the stock iPhone camera .

The 32mm lens is much larger and higher quality than the iPhone’s, and the f/1.8 aperture even allows for a relatively shallow depth of field without the drawbacks of Portrait Mode on dual-lens iPhones. It’s not quite at DSLR level, but it’s a huge improvement over the built-in camera. The DxO One a winner for amateurs and serious photographers alike.

For high-ISO shooting, DxO recommends shooting in its proprietary SuperRAW format, which takes four exposures and merges them in software for improved noise performance. We tested it at the highest ISO possible — 51,200 — and while the unprocessed file was a mess, it was quite good after we ran it through DxO software. JPEGs are another story; we wouldn’t push those above ISO 3,200, although they definitely still look better than the stock iPhone camera.
