[2] The DxO ONE had a 1-inch format, 20.2 megapixel image sensor[3]—the same one found in the Sony Cyber-shot DSC-RX100[4]—and an f/1.8 maximum-aperture lens and high-speed shutter.

However, the DxO ONE is not shaped like a lens, and it is easier to use as a standalone camera because it has a low-resolution black-and-white screen that can display live view.

The DxO ONE could be used on its own, with its rear OLED screen allowing the user to switch between photo and video, but not to preview the image.

[19] For desktop processing of raw and SuperRAW images, an Apple Mac or Windows computer was required.

Images were transferred using a separate application, DxO Connect,[20] via cable (or by directly using the microSD card that was used in the camera).
