Sony has introduced the Xperia 5 IV smartphone, which offers many features of the 
flagship model Xperia 1 IV in a more compact design; however, it has not inherited the periscope camera. On the other hand, it can also be used as a preview monitor on a Sony Alpha camera.
The camera array from the predecessor remains largely unchanged, but all modules are now supposed to be read out with fast 120BpS (previously only with the 24mm). The 24mm main camera with F1.7 has a rather large 1/1.7" sensor for cell phones. The wide-angle camera with 16mm F2.2 has a 1/2.5" sensor, and the telephoto module with 60mm F2.4 has a 1/3.5" sensor (all focal lengths are Kb-equivalent). The resolution is 12MP throughout, including the front camera. It can now be used to record selfie videos in 4K HDR.
As the first smartphone in the Xperia 5 series, the Xperia 5 IV offers real-time autofocus derived from the Alpha cameras and real-time tracking on all lenses (as on the Xperia 1 IV). Stabilization is via optical SteadyShot with FlawlessEye (24mm/60mm). It also supports up to 5x slow-motion shooting in 4K (120 frames per second).
In the Videography Pro mode - which offers a variety of manual settings - it is possible to transfer content directly to streaming services, just like in the Xperia 1 IV. The Xperia 5 IV can also be used as an external monitor: If it is connected to a mirrorless camera (for example, the Alpha models), the pictures recorded with the camera can be played back and reviewed in high quality directly via the Xperia 5 IV4.
Cinematography Pro "Powered by CineAlta" is also on board again and allows recording movies with parameters and color settings similar to those of professionals - various presets as well as free design options are available for this.
As in the flagship Xperia 1 IV, the Music Pro function is also included. With its cloud-processing AI capabilities, it should be possible to produce professional audio recordings - voices recorded with the new smartphone should be able to be converted as if they were recorded in a professional studio with Music Pro, according to Sony.
The Xperia 5 IV features a 6.1-inch FHD+ HDR OLED display with a 21:9 aspect ratio, which is said to be up to 50% brighter than the previous model's display. Overexposed and underexposed areas are supposed to be displayed optimized via real-time HDR.
The smartphone is equipped with the Snapdragon 8 Gen 1 Mobile platform as well as a larger 5,000 mAh battery with up to 3 years of battery life. Thanks to Corning Gorilla Glass Victus on the front and back, as well as IP65/68 (water and dust resistant), the Xperia 5 IV is robust.
The Sony Xperia 5 IV will be available from mid-September 2022 at a price of 1,049 Euros.
