Now the QX devices have competition in the form of the ONE by DxO.
The One uses Sony's 1 inch, 20 megapixel sensor, the same as in the RX100. The gadget has a fixed focal length, f/1.8 lens, and can capture RAW or compressed JPEG format. The One plugs into an iPhone using a swiveling Lightning connector. The One includes its own microSD card storage. JPEG exposures can also be saved in the iPhone camera roll.
From DxO's press release: "A free iOS app enables control of the individual settings on the DxO ONE camera, including aperture (from f/1.8 to f/11), shutter speed (from 15s to 1/8000s), and ISO (from 100 to 51200)...various capture modes, including multiple Scene modes, Speed, Aperture Priority, or full Manual mode..The DxO ONE also records outstanding videos at 1080p/30fps or 720p/120fps."
MSRP for the 3.8 oz (108 g) and 2.65” (6.9 cm) tall device is $599, delivery to begin in September.
