Sony Xperia Z1.

The Xperia Z1 is at the top of the smartphone camera pile with a 20-megapixel sensor, the same area as a compact camera. The f2.0 lens is housed in a waterproof body that is large by smartphone standards, bigger even than the Nokia 1020. The 12.5cm display has a very high 441ppi resolution. There is 16GB of internal memory and a microSD slot for an additional 64GB. Construction is elegant, with a metal surround on the body, but the white model we’re testing feels slippery. The camera can be used in full automatic mode or in manual and there is a physical shutter release.
The ”Triluminos” display is excellent. Image quality is top notch with sharp detail and consistent exposure and colour. The high resolution permits a modest digital zoom.
The phone body is angular and we do not find it comfortable to hold. The placement of the lens is right where the left index finger hangs over the edge. We took a lot of finger pictures.
DxO Labs ranks the Xperia Z1 No. 2 on its Mobile Mark scale, between the Nokia Pureview and the iPhone 5s. It feels as though there is a great camera struggling to get out of a good camera. The 20mp image is reduced to 5mp for output and degraded slightly in the process. Google has announced that future versions of Android will have RAW output in the camera module and the combination of outstanding camera basics and the promise of an Android upgrade make the Xperia a winner.
