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. Go beyond basic with 33-Megapixel full-frame sensor for outstanding still image and 4K movie quality
The full-frame 33MP Exmor R™ back-illuminated CMOS sensor delivers outstanding speed and superb image quality. The use of copper wiring contributes to higher transmission speeds and faster AD (analogue to digital) conversion, while fast sensor readout enables 10-bit 4:2:2 4K recording up to 60p. The sensor also provides improved color reproducibility, low-noise performance at all sensitivities, 15+stop3 dynamic range and increased AF (autofocus) speed and precision performance. Experience improved levels of color gradation and detail rendering as well as soft, natural-looking human skin textures.
BIONZ XR™ image processor for up to 8x2processing speed
The BIONZ XR engine, also used in the Sony Alpha 1 and Alpha 7S III models, provides up to an 8x2increase in processing speed. The engine concentrates real-time processing of AF (autofocus), image recognition and image quality adjustment to minimize processing latency for greatly increased movie and still processing power. User interface, network and file management processing is distributed to deliver fast response regardless of real-time processing load.
Beautiful images with reduced noise
Building on the capabilities of the back-illuminated Exmor R™ image sensor, the powerful BIONZ XR™ processing 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-stop dynamic range
Taking advantage of the camera's full dynamic range of 15 stops3, the Alpha7 IV uses image data from the sensor's 33-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.
4K 60p recording, 4:2:2 10-bit recording
The Alpha 7 IV gives you an impressive range of video recording options. Full pixel readout without binning allows 4K 60p11 recording in Super 35 mode providing high-resolution smooth footage that can be edited to 2x and 2.5x slow-motion when rendered to 30p or 24p in post-production, and 4K 24p or 30p full pixel readout without binning in full-frame with 7K11 oversampling. For highly detailed and rich 4K content.
Sony's smart AI-based Real-time Tracking
The superior power of the BIONZ XR™ processing engine has led to improvements in both Real-time Eye AF and Real-time Tracking9 features. Improved face detection translates into 30% better eye-detection accuracy compared to Alpha 7 III. AI (Artificial Intelligence) is used to detect and track the eyes and face of the subject (human, animal or bird)10 with extremely high precision. Real-time Tracking allows you to select your subject and then leave tracking to the camera, relying on the latest subject recognition algorithm and high-speed analysis of spatial data by the processing engine.
Improved Real-time Eye AF
Keeping the targeted eye in focus so you can concentrate on composition. The high speed of the latest image BIONZ XR™ 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.
Real-time Eye AF for birds for stills and movie
The Real-time Eye AF function is now capable of detecting the eyes of birds10 and tracking them in real time, for both still shots and movies. The BIONZ XR™ processing engine runs optimized AF and tracking algorithms to ensure uninterrupted tracking even for birds in flight, whose movement is hard to predict. Once you've selected a bird, the camera will automatically detect and precisely track that bird's eye, whether the bird is perched or in flight.
Instantly turn your Alpha 7 IV into a live streaming web camera
All it takes is a USB connection to turn the full-frame Alpha 7 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. You can choose from four different output formats, including high-resolution 4K video and simultaneous internal recording is also available, giving you broad flexibility to cover a wide variety of needs.
