The DSC-QX100 Digital Camera Module for Smartphones from Sony is an innovative camera that combines DSLR-like image quality with the ever-present convenience and sharing capability of the smartphone. With a 20.2MP 1.0" Exmor R Backside-Illuminated CMOS sensor and the BIONZ image processor, the QX100 creates sharp, high-resolution images with effective low light capabilities at ISO sensitivities that run to 12800 and are expandable to 25600.
What is original about the QX100 is its form factor. It looks less like a camera and more like just a lens. However, despite the fact that it has no viewfinder or LCD, it is indeed a camera. Its innovation is that it can be clipped directly to almost any smartphone and via its built-in Wi-Fi connection, utilize the phone's large display screen for composition and playback viewing and touch menu control. It can also be used off the smartphone, either handheld or mounted utilizing its integrated tripod thread.
The lens of the QX100 is the 3.6x optical zoom Carl Zeiss Vario-Sonnar T* f/1.8 lens which has the 35mm format equivalence of a 28-100mm lens. Its focal range includes wide-angle to portrait length telephoto and its maximum aperture at the wide-angle end is effective in low light and able to create a shallow depth of field.
The built-in Wi-Fi of the QX100 connects to your iOS or Android smartphone and once the Wi-Fi connection is established and the free PlayMemories Mobile App is installed, your phone will act as viewer and menu control for the camera. With Android smartphones, NFC (Near Field Communication) enables a Wi-Fi connection with just a simple tap between the phone and camera. Furthermore, with the Wi-Fi connection enabled, you can use your smartphone as a remote control and shoot with the camera detached from the smartphone. Also, thanks to a physical zoom lever and shutter button on the camera, you are able to shoot without a smartphone and view your images later. Images are saved to both the camera's memory and the smartphone's memory.
