Newly developed 33‑MP1 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 megapixel1 Exmor R CMOS image sensor provides high-speed readout, high sensitivity, low noise and highly accurate colour 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 colour reproduction. Fast processing speeds facilitate comfortable continuous shooting as well as responsive operation while performing data transfers.

Higher resolution, better colour reproduction

The new 33‑MP1 image sensor and processing engine raise the bar for image quality

In addition to boasting a larger pixel count and higher resolution than the α7 III, the α7 IV and its powerful Exmor R sensor represent a significant evolution of Sony’s original image technology, for improvements that go beyond mere numbers. Experience new levels of colour gradation and detail rendering as well as soft, natural-looking human skin textures.

Beautiful images with reduced noise

Building on the capabilities of the back-illuminated image sensor the BIONZ XR engine reveals even higher subjective resolution combined with exquisite detail and texture even in medium- and high-sensitivity ranges. Impressively low levels of noise are achieved throughout the standard range of ISO 100-51200 (expandable to ISO 50-204800 for stills and ISO 100-102400 for movies).

Wide, 15-stop2 dynamic range

Taking advantage of the camera’s full dynamic range of 15 stops2, the α7 IV uses image data from the sensor’s 33.0 megapixels1 to render remarkably delicate detail in landscapes and scenery. This stunning image quality is based on Sony’s unrivalled experience at the front lines of both still-image and movie creation.

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 HEIF3 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 colour depth provides realistic reproduction of skies and portrait subjects where subtle, natural gradation is essential.

5-axis optical image stabilization

Up to 5.5-step4 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 steps3 of shutter-speed compensation, to maximize the high-resolution performance of the camera’s 33.0‑MP1 image sensor.

Fast Hybrid AF, evolved

The Fast Hybrid AF system, combining phase-detection AF and contrast-detection AF, has evolved even further to achieve greater speed, accuracy and tracking performance. With Sony’s 4D FOCUS, a wide, dense AF area covers roughly 94% of the image area for both stills and movies with 759 phase-detection AF points.

Sony’s smart AI-based Real-time Tracking9

Sony’s unique subject recognition algorithm uses colour, 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.

Improved Real-time Eye AF

Keeping the targeted eye in focus so you can concentrate on composition

The high speed of the latest image-processing engine provides a significant boost to Real-time Eye AF performance, even when the subject is looking up, down or sideways. It is also possible to use Touch Tracking to initiate Real-time Tracking of any subject in the frame, simultaneously initiating Real-time Eye AF if an eye is detected, simply by touching the screen

Pet photos made easy

Fast, accurate focus for difficult animal shots

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.

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—simply preset the subject to “bird”. 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.

Focus Map to visualize depth of field

Answering a request from professional creators, the brand-new Focus Map feature lets you easily visualize depth of field when you’re shooting19. In use, focus (depth map) information is overlaid on a display of the live view in real time, so you can easily see which areas are in or out of focus.

Choose your look, for more expressive movies

Support for S-Cinetone, Creative Look and S-Log3

The S-Cinetone colour matrix, based on technology acquired through development of CineAlta cameras such as the VENICE, produces an impressive look with beautiful skin tones without post-editing. The Creative Look presets create other interesting visual moods in-camera, or you can use S-Log3 gamma to access the camera’s full dynamic range (15+ stops17) for smoother post-production workflows.

Next-level image quality with 10-bit 4:2:2 recording

Make in-camera recordings with the amazing richness of 10-bit depth and 4:2:2 colour sampling, with either Long GOP or All-Intra frame encoding, for far greater flexibility in image grading, post-processing and compositing.

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 USB26, select “Live Stream (USB Streaming),” and you’re set.
