Sony has announced the A7 IV, a new model in its series of mirrorless system cameras with a full-frame sensor and E-lens mount. The device has a new 33MP sensor and gets the top-of-the-line Bionz XR processor. It should ensure better autofocus.
Sony provides a file A7 IV As a hybrid device suitable for both photography and video. The 33-megapixel sensor has an ISO range of 50 to 204,800 and there are 759 phase-detection points for autofocus on the sensor, covering 94 percent of the frame. According to Sony, the sensor has fifteen degrees of dynamic range.
The A7 IV contains the Bionz XR image processor, which Sony launched at the beginning of this year Top Model Alpha 1 Foot. As a result, the camera can now automatically focus on the eyes of birds and other animals, as well as the eyes of humans. Detection of people’s faces and eyes is also improved by 30 percent compared to the A7 III’s camera, according to the manufacturer.
Filmmakers can use the camera in Super35 mode, which is compatible with the APS-C format, for 4K and 60fps shooting. When using the full sensor, the A7 IV records at 4k at 30fps, but uses 7k oversampling: the sensor uses all the pixels when shooting and downgrades them to 4k. This results in a clearer picture.
The A7 IV also gets the S Cinetone feature from Sony Cinema and S-Log 3 cameras, for capturing video files with more room for post-processing. The camera records with 10-bit color depth and 4:2:2 color sampling.
Sony will launch the A7 IV in December in the Netherlands and Belgium with a suggested retail price of €2,800. There will also be a kit with the SEL 28-70mm f / 3.5-5.6 OSS lens, for 3000 euros. So the introductory price is much higher than the price of Sony A7 IIIWhich was introduced at the beginning of 2018 and came out with 2,300 euros. This device with a 24-megapixel sensor currently costs about 1900 euros.
