Basic Has Never Been This Good

Prepare to be inspired. The α7 IV's true-to-life resolution and remarkable AI-powered autofocus complement a range of world-class features at the cutting edge of imaging technology.

Newly Developed 33‑MP Full-Frame Back-Illuminated CMOS Image Sensor

Delivering outstanding performance and excellent image quality in both stills and movies, the α7 IV's new 33.0 megapixel Exmor R CMOS sensor provides high-speed readout, high sensitivity, low noise, and highly accurate color reproduction.

Flagship-Level Image Processing with BIONZ XR

The α7 IV uses the latest image processor to offer greatly enhanced performance, with improved image quality and color reproduction. Fast processing speeds facilitate comfortable continuous shooting as well as responsive operation while performing data transfers.

Quickly Set the Visual Mood with Ten Creative Look Presets

A selection of ten Creative Look presets and eight parameters can quickly craft a mood for your still images, movies, and live streams. And since no post-editing is needed, you can share your vision immediately after shooting.

10-bit HEIF Still-Image Format for Smooth Gradations

Along with conventional RAW and JPEG, you can choose the HEIF (High Efficiency Image File) format for still-image capture. Smooth 10-bit color depth provides realistic reproduction of skies and portrait subjects where subtle, natural gradation is essential.

5-Axis Optical Image Stabilization

Up to 5.5-step shutter-speed compensation from the in-body stabilization unit. The α7 IV's high-precision stabilization unit and gyro sensors work together with image-stabilization algorithms to achieve up to 5.5 steps of shutter-speed compensation, to maximize the high-resolution performance of the camera's 33MP image sensor.

Sony's Flash Units Coordinate with the Camera's Face-Detection System

Sony's latest flash units communicate fully with the α7 IV, leveraging its powerful face detection capabilities to adjust exposure to produce natural-looking skin tones. Precise white-balance synchronization and P-TTL metering, at up to the "Hi" level of continuous-burst speeds, reliably expose even fast-moving subjects with quick lighting changes, for unmatched dependability and creative possibilities.

External Control of Flash Units

The α7 IV Ver 1.1 supports separate registration of shutter speed and ISO sensitivity for flash on/off. For greater convenience during shoots, compatible flash and radio wireless commander units connected to the α7 IV can now be controlled directly from the camera interface.

Sony's Smart AI-Based Real-Time Tracking

Sony's unique subject recognition algorithm uses color, pattern (brightness), and subject distance (depth) data to rapidly process spatial information in real time. AI is used to detect and track the eyes and face of the subject (human, animal, or bird) with extremely high precision. Just select the subject to track, then leave it to the camera.

Pet Photos Made Easy

By setting the camera's subject detection type to "Animal" in advance, you can automatically detect and track an animal's eyes, for greater success in both wildlife shots and photos and movies of your pets at home. Animal-eye detection has been improved, with reliable tracking and accurate focus even when the animal's face is upside down.

Real-Time Eye AF for Birds

Bird-eye detection supported for both still shots and movies. For the first time in the α series, bird-eye detection is available in movies as well as still shots. The camera's astonishing speed and precision allow automatic tracking of a specific bird, whether it's perched somewhere or in flight, keeping the eye in steady focus despite any fast and unpredictable movements.

High-Performance 'Active Mode' Image Stabilization

Active Mode stabilization for movie shooting is built on the camera's highly accurate stabilization unit, gyro sensors, and sophisticated algorithms. It precisely detects the required amount of compensation and applies stabilization, providing stable 4K movie shooting without compromising the α7 IV's compact size and mobility.

Instantly Turn Your α7 IV into a Web Camera

All it takes is a USB connection to turn the full-frame α7 IV into a high-performance webcam. There's no need for complicated advance setup, just connect the camera to a computer or smartphone via USB, select "Live Stream (USB Streaming)," and you're set.

Share Your Still Images and Movies Immediately

The α7 IV is designed to make sharing easy, so you can share your fresh images, and your vision, with the world immediately.

Improvements in Selection and Editing Workflow

The α7 IV incorporates a number of individual improvements to image selection and editing, adding up to smoother overall workflow that allows large amounts of data to be efficiently managed.
