The Sony Cyber-shot DSC-QX100 is a mobile device-mountable lens-style compact camera manufactured by Sony.

Announced on September 3, 2014, the QX100 is one of Sony's "Smart Lens" cameras, alongside the QX1, QX10 and QX30, that are specifically designed to be used with a smartphone.

Its highlight features are its 1-inch (13.2 x 8.8 mm) backside-illuminated Exmor R CMOS sensor, with 20.2 megapixels, ƒ/1.8 to ƒ/4.9 Carl ZEISS® Vario-Sonnar T* lens and a 3.6x (28–100 mm) optical zoom, all taken straight from the Sony RX100 II premium compact camera.
