The new 33MP 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 color gradation and detail rendering as well as soft, natural-looking human skin textures.
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).
Taking advantage of the camera's full dynamic range of 15 stops, 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.
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 33.0MP1 image sensor.
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 7596 phase-detection AF points.
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. The eye-tracking is not reserved only for humans, it works on animals as well.
Bird-eye detection is 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 bird10, whether it's perched somewhere or in flight, keeping the eye in steady focus despite any fast and unpredictable movements.
It is now possible to record movies at up to 4K 60p 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.
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+ stops) for smoother post-production workflows.
The a7 IV leverages our parallel lens and camera development to provide innovative Focus Breathing Compensation, exclusively for Sony’s E-mount lenses. By minimising the field-of-view shift that can occur, during movie shooting, when you rack focus with some lenses, you can achieve impressive results – for new creative possibilities from a diverse range of Sony’s E-mount lenses.
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.
Inherited from the Cinema Line FX6, the AF Assist function smoothly switches between auto and manual focus. Rack focusing is possible by rotating the focus ring to switch into MF and shift focus to a different subject, with AF resumed when ring rotation stops.
Fine-tuned focus features, also used in higher-end models like the α1 and the α7S III, enable creative movie options like rack focus, quick switches of AF target, and highly customisable subject tracking sensitivity.
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.
All it takes is a USB connection to turn the full-frame α7 IV into a high-performance webcam. There's no need for a complicated advanced setup, just connect the camera to a computer or smartphone via USB, select "Live Stream (USB Streaming)", and you're set.
The α7 IV is designed to make sharing easy, so you can share your fresh images, and your vision, with the world immediately.
