Verdict

The DxO One is a pocket-sized camera designed to attach to iOS devices via a Lightning connector, featuring a 20.2-megapixel 1-inch BSI-CMOS sensor and a fixed 32mm equivalent f/1.8 aspherical lens with a 6-blade iris. It offers full manual controls (PASM), an ISO range of 100 to 51,200, shutter speeds from 1/8000s to 15s, and supports RAW as well as a specialized 'SuperRAW' format for advanced noise reduction. Main pros include its extremely compact aluminum unibody, DSLR-level image quality in a mobile form factor, and a swivel mount that allows for creative shooting angles. However, notable cons include a short battery life of approximately 200 shots, a tendency to overheat during extended use, the lack of an optical zoom or built-in flash, and an initially high price point.
