The DxO One is a unique camera. Like the Sony QX cameras, it depends on a smartphone for its viewfinder/display and controls, but the One is iPhone-only and connects via the Lightning port rather than WiFi. For years, special guest Alex Lindsay has begged for camera manufacturers to decouple the optics and sensor from the user interface, allowing third parties to provide a variety of controllers to meet a variety of needs. The One doesn’t go quite that far — there’s no API for others to write controlling iPhone apps — but it delivers a much improved experience as compared to the Sonys.

The DxO One has a 1″ 20MP sensor and a 32mm (full-frame equivalent) f/1.8 lens with an adjustable (to f/11) aperture, shutter to 1/8000 second and ability to shoot to ISO 12,800 (normal mode), delivering image quality much improved over that of even the latest iPhones. Of interest to serious photographers will be that the One can capture RAW files as well as JPEGs. And if you don’t need to see the image while shooting, you can even use it without the iPhone. (The camera holds a microSD card.)

  • Thanks for the review of the DxO One. I have one and while I haven’t been blown away with it, I do like it and the image quality seems pretty good. I’m sure it’ll be even better as I get used to it. The thing I CAN say is it’s ALWAYS in my pocket, ready to go. I find, however, that I tend to take it out and shoot rather than take time to hook it to my iPhone. I wish that itty bitty screen on the back actually worked as a screen just big enough for me to be sure of my composition and not cutting off someone’s head. I’d still want to connect it to my iPhone when I wanted better image preview and, of course, access to the other shooting functions and settings.

    Do you have any sample images from the DXO One you can share? Whilst DXOs samples are very compelling, I thought the examples on Amazon looked extremely washed out. Whilst I’m tempted the samples I’m finding online seem a lesser quality than my Fuji X30 produces, which for a prime with a 1″ sensor doesn’t seem right! It takes a minute or so to Wi-Fi my X30 to my iPhone, so unless there are extremely obvious differences in image quality, I’m struggling to find a good reason to buy the DXO One, tempting as it is, as a form factor.
