The DxO One is the perfect compromise for people who want to get better pictures but don't want to be weighed down by a lot of gear. No matter how good it is, every third-party iPhone lens faces the same reality: It just doesn't take images as good as the ones from a real camera. After 2 minutes of inactivity, the camera turns off. To conserve battery life, the DxO goes into power-saving mode after 50 seconds of inactivity. Battery LifeĭxO estimates that the One's battery will last through about 200 photos - a claim I found to be fairly accurate. Even more clever is a live preview mode while the DxO's miniscule screen shows only a very pixelated black-and-white image, it helps give you some sense of what you're aiming the camera at. In this mode, the DxO's display turns into a touch screen, and lets you swipe between camera and video modes. Stand-Alone ModeĪ neat trick with the DxO is that you can use it even when it's disconnected from your iPhone, making it fantastic for impromptu and surreptitious shots. Most likely, I was stretching the processing power of the DxO to its limit. However, while filming, the video feed from the DxO to my iPhone was jittery, especially as I panned around. Colors were well saturated, with the exception of yellow daffodils, which looked blown out. A video I shot of a rainy Bryant Park was detailed and in focus.

You'll get a faster response from a camera such as the Sony A5100, but then again, the DxO isn't meant for sports photography. While not a speed demon, the DxO was ready to shoot about half a second after taking a photo. You can also tap on any part of your iPhone's screen to have the DxO focus on that point. But occasionally, it was confused, especially in darker situations. The DxO was generally quick to focus, usually taking about a second to do so. I was pleased with the evenness of the lighting, as well as the details in a picture of a woman with the New York skyline in the background. In low-light conditions, the DxO managed to capture well-defined images. (Image credit: The DxO was able to capture this scene with only a streetlamp for illumination.
