The Sony Xperia Z1 was announced during the MWC 2014 and therefore it is the company’s flagship for the year of 2014. The spec sheet shows a very subtle bump with an upgrade in terms of processor, screen size and RAM.
The camera and optics used are said to be the same, however, the Z2 that has a 20.7-megapixel backside illuminated 1/2.3-inch Exmor RS sensor just like the Z1, appears to reveal pronounced improvements in the Z2′s image quality. Noise levels seem substantially reduced, and the images are overall more crisp and detailed.
So does this mean a software update can improve the Z1′s image quality? We’re definitely optimistic about it!
