This week Sony Announced Xperia 1, the successor to their previous flagship the Xperia XZ3 with a few new features and a very ultra-wide 21:9 CinemaWide™ 4K HDR OLED display which creates cinematic like aspect ratio UHD video with what they claim Cinealta HDR color science. The footage does look impressive at first glance but we have to remember the small sensor on phones simply cannot compete with an APS-C or Full Frame Cinealta camera sensor.
The good news is that the phone continues to offer the 960fps Full HD 1080p spec as in previous phones the XZ series. Sony chose to not allow initial samples of footage shot in various modes including the high speed because the phone is not finalized. From anecdotal evidence, it seems to compare favorably with their Xperia XZ3 but with some better color characteristics due to the Cinealta heritage color LUTs.
