Introduced with the first-ever continuous optical zoom capability on a smartphone, Sony Xperia 1 IV is garnering attention from many users regarding its photo and video quality. So, equipped with what it offers, does Xperia 1 IV satisfy users?

1. Features on the camera of Sony Xperia 1 IV
The Sony Xperia 1 IV phone is equipped with a main camera module consisting of 3 lenses:
- The main Wide camera features a 12 MP Sony IMX 557 sensor, f/1.7 aperture, 24mm focal length, 1/1.7″, 1.8µm, Dual Pixel PDAF, and optical image stabilization (OIS);
- The Telephoto camera features a 12 MP Sony IMX 650 sensor, variable aperture from f/2.3 to f/2.8, variable focal length from 80mm to 128mm, 1/3.5″, Dual Pixel PDAF, continuous optical zoom from 3.5x to 5.2x, and optical image stabilization (OIS);
- The Ultra wide angle camera is equipped with a 12 MP Sony IMX 563 sensor, f/2.2 aperture, 124˚ field of view, 16mm focal length, 1/2.5″, and Dual Pixel PDAF;
Additionally, the device is equipped with a ToF Sony IMX 316 depth sensor along with an RGB infrared sensor with precise white balance adjustment function.
The Sony Xperia 1 IV phone also features a 12 MP front camera, f/2.0 aperture, 20mm focal length (wide), 1/2.9″, and fixed focus.
It can be said that the camera setup on the Sony Xperia 1 IV phone does not differ from its predecessor, the Xperia 1 III, however, it changes in some aspects, specifically:

- Firstly, regarding the Telephoto camera
Despite still using a 12MP sensor and having 2 zoom levels, instead of:
In the Xperia 1 III, the telephoto camera has 2 zoom levels: 2.9x (70mm focal length and f/2.3 aperture) and 4.4x (109mm focal length and f/2.8 aperture)
In the Xperia 1 IV, there are 2 zoom levels: 3.5x (with an 85mm focal length and f/2.3 aperture) and 5.2x (with a 125mm focal length and f/2.8 aperture).
But the noteworthy aspect here is that users can continuously zoom between these two ranges similar to using optical zoom on digital cameras. There is no digital zoom here, and the ability to zoom endlessly here is purely technical. And this is a feature that is almost 'unique' on a phone up to this point. Of course, this will support the impressive zoom capability on the Xperia 1 IV phone.
- Secondly, regarding the video recording capability
The device is equipped with an extended contrast range for video - operates independently with HDR mode, so you can turn this feature on or off when using SDR or HDR as desired.
Alongside the introduction of Xperia 1 IV, Sony also unveiled two accessories for smartphone filmmaking: the Shooting Grip and Vlog Monitor - enhancing video shooting and vlogging on the phone.
