Sony has been the target of numerous leaks in recent times and their next flagship, the Sony Xperia Z4, has been leaked in renders and real life photos. These days we got the first picture that was supposedly taken by this smartphone and while there's no way to prove its authenticity, the EXIF data suggests that it was taken by a phone made by Sony with model number E6553, which has been associated with the Xperia Z4.
Today, two more photographs were spotted on the same forum where the first one was found, that carry that same model number with the same resolution of 5248 x 3936, making it almost the 20.7 megapixels, the sensor's size that's supposed to be included in this phone. If the landscapes seen in the pictures seem familiar with the last one it's because the GPS location suggests that they were indeed taken at the same location in the UK.
Details in the new photographs seem fairly decent, but when looking at them at full size, some digital noise can be noticed. Still, this could be because they were taken with a prototype of the phone or the software used to process the images may not have been finalized, so there could be some improvement when the phone finally launches. Once again, there's no way to know for sure if we are actually looking at pictures taken by the Xperia Z4, but the phone is definitely been developed and tested out there as the leaks become more and more frequent.
Sony always pointed out the cameras in their recent flagships as one of the main selling points, but they don't seem to have improved much compared to the ones taken by older models, and with the design being almost identical as the one from the previous model (if what the leaks show is real), they must come up with some new features to make users want to upgrade to the new flagship. Sure, some users will like the rumored QHD display, but some others won't notice and will have a hard time telling the new phone from last year's model.
