Sony A7 IV Body

A newly developed 35mm full-frame back-illuminated CMOS image sensor with approx. 33 effective megapixels and the latest generation BIONZ XR flagship-class processing engine, lets the Sony A7 IV Body realize flagship-class still image quality with advanced AI-based autofocus at an impressive 10 fps continuous shooting rate plus evolved real-world movie features including 10bit 4:2:2 Colour, S-Log3/S-Cinetone and full-frame 7K oversampled 4K30p internal video recording.

Improving on its popular predecessor A7 III, the new A7 IV receives the updated 759 phase-detection AF point 4D Focus system of the Sony A1 thus reducing the time required to refocus by 30% compared to the A7III. The newly developed subject recognition algorithm uses colour, pattern and subject distance data for more tenacious real-time tracking and Real-Time Eye AF now supports birds as well as Human/Animal mode. 5-axis optical in-body image stabilisation has also been improved with up to 5.5-steps of shutter speed advantage.

With the A7 mark IV, Sony has yet again proved that they take video content creation seriously. The A7 IV is capable of 4K60p Video Recording (16:9) with a 1.5x crop using 4.6K Oversampling and 4K30p Full-frame Recording (16:9) without crop using 7K Oversampling, both modes support shooting with 10/8bit, Long GOP/All-I and H.264/H.265. S-Cinetone Picture Profile offers more expressive depth and natural skin tones while S-Log3 enables 15+ stops of latitude to protect high-light details in your footage for a natural roll-off.

A new Focus Map overlay lets you easily visualize depth of field quickly during shooting with a coloured overlay showing behind the focus, within focus and in front of focus. While AF Assist with flexible 7-step AF Transition Speed and 5-step AF Subject Shift Sensitivity supports focus transitions when using AF.

Focus breathing can be a distraction for your viewers with the frame jumping around during focusing. Sony A7 Mark IV uses Breathing Compensation with supported lenses to combat this keeping a consistent angle of view when focusing.

Other features that make the A7 IV the content creators dream camera include a bright and clear 3.69 million dot EVF, a 3.0-inch 1.03 million dot Vari-angle LCD screen that is fully adjustable, dual card slots (CFE-Type A/UHS II + UHS II), a Digital Multi-Interface Shoe supporting Digital Audio, USB 3.2 (Gen 2) Connectivity with up to 10Gbps transfer and USB-PD Charging, Mic input + Headphone output ports, Wi-Fi 2.4GHz/5GHz plus Imaging Edge Mobile Connection via Bluetooth, and easy to use 4K 15p & FHD 60p Live Streaming with internal recording via UVC (USB Video Class) /UAC (USB Audio Class) streaming function.

• 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.
