Sony Xperia Z2 overview: Revised model takes first place in Mobile rankingsBy Kevin Carter - Monday April 07 2014 Mobile Review
While the previous Sony Xperia Z1 is still the highest rated camera-phone for video capture, the new Z2 model still impresses and has the added benefit of Ultra HD 4K recording. (it is worth noting that 4K was not evaluated)
While the image quality is good particularly regarding texture reproduction and noise levels, Sony hasn’t yet implemented step-less AF for smooth changes in focus position, which is distracting at best. Clips also revealed visible color shading, a curious presence after the near total removal in stills. There were also some white balance errors when large areas of grass and foliage were included in scenes.
Overall then, the Sony Xperia Z2 is strong on stills quality and only slightly less so when it comes to video capture. That’s unlikely to make users pause for thought given the obvious attraction that 4K has, though don’t forget you’ll need a suitably equipped TV to benefit fully.
Those that aren’t tempted by video, however, but regularly use their phones for stills won’t be left wanting.
