The Alpha 7 IV gives you an impressive range of video recording options. This stunning image quality is based on Sony's unrivalled experience at the front lines of both still-image and movie creation. Taking advantage of the camera's full dynamic range of 15 stops, the Alpha7 IV uses image data from the sensor's 33-megapixels to render remarkably delicate detail in landscapes and scenery. 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). Beautiful images with reduced noiseīuilding 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. User interface, network and file management processing is distributed to deliver fast response regardless of real-time processing load. 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. The BIONZ XR engine, also used in the Sony Alpha 1 and Alpha 7S III models, provides up to an 8x increase in processing speed. BIONZ XR™ image processor for up to 8x processing speed Experience improved levels of color gradation and detail rendering as well as soft, natural-looking human skin textures. 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. 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 60p11.
The full-frame 33MP Exmor R™ back-illuminated CMOS sensor delivers outstanding speed and superb image quality.
