Share the moment as it happens

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.

Still photography without compromise

Higher resolution, better colour reproduction

The new 33MP1  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.

Enhanced resolution and colour Low noiseWide dynamic range

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 stabilisation

Up to 5.5-step4  shutter-speed compensation from the in-body stabilisation 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.

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 tones5. Precise white balance synchronisation 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 

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. 

Reliable autofocus, impressive speed

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 7591 phase-detection AF points.

10-frames-per-second2 continuous shooting with fast buffer release 

Both the mechanical and electronic shutters allow you to shoot more than 800 frames 3& at up to 10 fps2 with AF/AE tracking, thanks to the α7 IV's high-capacity buffer memory, speedy BIONZ XR processor, and improved memory card writing speed.

Sony's smart AI-based Real-time Tracking4 and Real-time Eye AF

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 shots5

By setting the camera's subject detection type to "Animal" in advance, you can automatically detect and track an animal's eyes4, 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 birds5

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 bird5, whether it's perched somewhere or in flight, keeping the eye in steady focus despite any fast and unpredictable movements.

Movie imagery, moving ever forward

4K 60p1 movies with smooth, natural-looking capture

It is now possible to record movies at up to 4K 60p1 with full pixel readout and without binning, taking advantage of the α7 IV's brand-new image sensor and wide dynamic range for smooth images of fast-moving subjects.

7K2 oversampling for beautifully expressive, richly detailed images 

When recording 4K3 movies at up to 30p, full-frame 7K oversampling is possible, resulting in high-resolution, highly detailed 4K3. Select the mode that best suits your purpose, and let the camera deliver.

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.

All-Intra encoding supported in addition to Long GOP

All-Intra4 recording encodes every frame independently, at bitrates of up to 600Mbps5, capturing complex motion more accurately and allowing more efficient editing workflows.
