The DxO ONE from DxO is a small camera that attaches to a tablet or smartphone. It was originally compatible with iPhone and iPad using the Lightning connector port, and more recently with some Android phones. It was introduced in June 2015. The DxO ONE has a 1-inch format, 20.2 megapixel image sensor—the same one that is found in the Sony Cyber-shot DSC-RX100—and an f/1.8 maximum-aperture lens and high-speed shutter. The ONE uses the attached mobile device as an electronic viewfinder for the camera, which does not have its own viewfinder.
European Imaging and Sound Association awarded the DxO ONE its prize for photo innovation for 2015–2016. DxO has also created a website where photographers can showcase images taken with the DxO ONE.

The DxO ONE works with iPads and iPhones running iOS 8 or later and that have a lightning connector, and with some Android phones that have a USB-C connector. For proper connection between the mobile device and the DxO ONE, a case that does not occlude the area around the Lightning Connector is necessary. The DxO ONE can be used by itself, with its rear OLED screen allowing the user to switch between photo and video, but not to preview the image. This was later updated by firmware to allow the rear screen to be used as a framing assistant.
For desktop processing of raw and SuperRAW images, an Apple Mac or Windows computer is required. Images are transferred using a separate application, DxO Connect, via microUSB cable (or by directly using the microSD card that was used in the camera). Apple added support for processing DxO ONE raw files in Digital Camera Raw 6.17 and Adobe added support for them in Camera Raw 9.2.
