33MP high-resolution full-frame sensor
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+stop 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 8x processing speed
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. 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 stops, the Alpha7 IV uses image data from the sensor's 33-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.
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.
