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‑MP2 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 megapixel2 Exmor R™ CMOS image sensor provides high-speed readout, high sensitivity, low noise and highly accurate colour reproduction.
Higher resolution, better colour reproduction
The new 33‑MP 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-stop3 dynamic range
Taking advantage of the camera’s full dynamic range of 15 stops, the α7 IV uses image data from the sensor’s 33.0 megapixels 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.
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.
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 7598 phase-detection AF points.
10-frames-per-second continuous shooting with fast buffer release
Both the mechanical and electronic shutters allow you to shoot more than 800 frames (dependant on memory card speeds) at up to 10 fps 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 Tracking
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.
