The latest to be announced is the DxO ONE, which takes DSLR-quality photos on your iPhone or iPad. At just under 7 cm tall, and 108g light, the camera is small enough to fit into your pocket, and attaches to your iPhone or iPad via the lightning connector, turning the display into the camera’s viewfinder. Despite its size, the camera is capable of taking crystal clear images thanks to the f/1.8, 32mm equivalent aspherical lens, and comes with an iOS app which allows you to control the individual settings including aperture, shutter speed and ISO.
In the U.S., the DxO one can be pre-ordered now direct from the DxO website.
