It's no secret that smartphones have been threatening camera sales, but Sony has decided to embrace it by designing a camera specifically for smartphone photography. Essentially, the QX100 is a complete digital camera--minus the screen. The sensor and lens combo attaches to a smartphone and communicates with it using wi-fi (or Near Field Communication if the phone also happens to be a Sony). The entire user interface (i.e. navigating the menu) is on your phone. But the perk to smartphone photography is always having your camera with you, and while the QX100 is small, it's probably not a good idea to keep it in your pocket. And since everything is controlled through a wi-fi connection, the camera isn't particularly fast and only shoots at 1 fps. The ultimate reason to look into the QX100, though, is that it features the same large sensor and fast lens as the popular RX100--for about $200 less. There are several features, like RAW, manual modes and built-in flash, offered on the RX100 that are not part of the QX100 however. And with the absence of those features, only one manual mode and no manual ISO adjustment, most users would be happier picking up a wi-fi-enabled advanced compact with more control. If we graded this camera just on innovation, the sensor and the lens, it'd have an A+, but the lack of manual controls and custom shooting options is a big downside.
