High-resolution Oversampling delivers High-detail 4K Video

Evolved movie technology taken directly from real-world movie production ensures high image quality and high sound quality for the content shot with the A7 IV.

4K 60p recording in Super35 format with full pixel readout without binning and smooth 2.5x (max.) slow-motion imagery at 4K resolution provides new creative outlets for you filmmaking needs. While full-frame 7K oversampled 4K 30p recording with full pixel readout without binning delivers expressive full-frame video with more detail.

Optical Active Mode image stabilisation ensures smooth footage without image quality compromise and the A7 IV's digital audio interface delivers clearer audio recordings with minimal hassle when using the optional ECM-B1M Directional Mic or the ECM-W2BT Wireless Lav.

Flagship Video Features for Post-production and Quick Delivery

• 10-bit 4:2:2 colour sampling

• Real-time Eye AF for humans, animals, and birds | with Eye AF right/left eye selection (Human & Animal)
• AF Assist | supports focus transitions when using AF
• Focus Map | visualize depth of field quickly during shooting with a coloured overlay showing behind DOF, within DOF and in front of DOF
• Breathing Compensation* | for consistent angle of view when focusing

Sony A7 IV Live Streaming Features

UVC (USB Video Class) /UAC (USB Audio Class) streaming function provides easy connection and supports video & sound distribution in Real-time. This enables the Alpha 7 IV to function as a high-performance web camera when connected to a computer or smartphone via USB. A USB function selection menu will pop up on the camera display when the camera is connected to a computer.

• 4K 15p & FHD 60p deliver extremely high image quality and realism for remote sharing. (4K 15p, Full HD 60p, Full HD 30p, HD720 30p)
• Digital audio delivers high sound quality.
• Creative Look & Soft Skin Effect make an ideal impression in live streaming video to not only clients but also, friends and video viewers.
• Record internally while live streaming for added flexibility of distribution via SNS or a web page later.

Other Enhancements of the Sony A7 IV Camera

• New heat dissipating structure | As found in the Alpha 7S III and flagship Alpha 1, the Sigma shaped heat sink effectively draws heat away from the sensor to allow 4K 60p 10 Bit 4:2:2 recording continuously for over an hour.
• Shutter closed on Power-Off | This function closes the shutter when the camera’s power is turned off, protecting the image sensor from dust and particles while changing lenses.
• Improved Imaging Edge Mobile touch control | Touch Tracking and Touch Focus can be controlled from the Imaging Edge Mobile application*1, adding extra AF control versatility. The focus frame is now shown on the application display, further enhancing operability.
• Image Stabilization metadata | The A7IV records gyro and lens metadata that can be used in the Catalyst Browse/Prepare applications to apply post-shoot image stabilization.
• Display with external HDMI device | It is now possible to simultaneously display 4K video on three devices: the camera monitor, an external HDMI recorder/monitor, and the Imaging Edge Mobile app connected via Wi-Fi.
• Imaging Edge Mobile Connection via Bluetooth | If Imaging edge Mobile and the camera are paired in advance, the camera keeps connecting with IEM, and only needs to be selected from the IEM menu to allow Wi-Fi transfer of images stored in the camera.
• Improved transfer speed | The Imaging Edge Mobile application now supports 5 GHz Wi-Fi for higher transfer speeds on top of 2.4GHz.
• FTP background transfer with 5GHz wireless | Allows transferring still image and movie files to a specified remote FTP server via 5GHz wireless LAN, high-speed wired LAN via a USB to Ethernet adapter, or a USB-tethered smartphone connection.
• A SuperSpeed USB 10Gbps (USB 3.2 Gen2) Type-C connector allows fast, stress-free wired PC Remote (tethered) shooting.

Advanced External Flash Control

• P-TTL flash metering for every frame in Lo, Mid, and Hi continuous shooting mode ensures stable illumination and consistent exposure for each frame, even when tracking fast-moving subjects in scenes where the light changes dramatically or the angle of view is changed
• Reduced flash trigger time lag
• External flash control allows the control of compatible flash and radio wireless commander units connected to the camera directly from the camera interface
• Control linked to the camera’s face detection for AWB and flash level control gives a natural colour tone on human faces considering the balance between the light incident on the subject’s face from the flash and from the environment. When more than one person is in the shot, flash will be optimized for the individual’s face on which the face or eye detection frame is displayed.
