The Panasonic Lumix DMC-CM1 smartphone features a 1 inch 20MP sensor, which is likely the same imaging unit we've seen used by other recent high-end compact cameras like Sony's Cyber-shot RX100 III.
The large sensor is coupled with an F2.8 Leica lens that offers an equivalent focal length of 28mm. This is by far the best camera specification on any smartphone and the 20MP resolution should even allow for a good-quality digital zoom. The CM1 is also capable of recording 4K-video and Raw images. Focus, aperture, shutter speed, ISO and white balance can all be adjusted manually, and there's a mechanical click-wheel around the lens ' barrel' on the front of the camera/phone.
The rest of the specification is in line with current high-end smartphones. Images can be viewed and composed on a 4.7-inch 1080p display and Android 4.4 is powered by a Qualcomm Snapdragon S801 quad-core processor that is clocked at 2.3 GHz. 16GB of internal memory are on board but the device also takes microSD-cards of up to 128GB capacity.
