Sony Xperia Z2 vs iPhone 5s vs Lumia 1520 low-light camera comparison
Sony had a box for testing the low-light capabilities of its newly-minted Xperia Z2, with a 20.7 MP Exmor RS sensor, Sony G Lens, and BIONZ image processor. The handset offers plenty of shooting modes, including a low-light one, which automatically switches on if you are using the default Intelligent Auto mode of the handset.
That's exactly what happened at MWC, when the Z2 was set against the iPhone 5s, and the Lumia 1520, using the three phones in the same way - to snap a picture of the contents in a box, mimicking low-light conditions. The image from the Z2 looked much brighter, at least on the phone's display, as the LED flash fired up, indicating the phone's algorithms were reluctant to use slower shutter speeds, higher ISO, or a combination of both, with those smallish 1.1 micron pixels of the Z2's sensor.
The images from the iPhone and the Lumia looked more natural, as if they were indeed taken at night, which the dark box was meant to simulate. Of course, it is premature to draw any conclusions whatsoever, from pictures taken with demo units, and shown on the phones' displays only, so we'll wait to put the new handset though its camera review paces as soon as it arrives in the office.
