33MP back-illuminated CMOS full-frame sensor

Copper wiring contributes to higher transmission speeds and faster AD (analogue to digital) conversion. Fast sensor readout enables 10-bit 4:2:2 4K recording up to 60p. The sensor also provides improved color reproducibility, low-noise performance, 15+stop dynamic range and increased AF speed.

Sony a7 IV: Beyond BasicAn all-arounder that pushes beyond basic, the Sony a7 IV does double duty with strong stills and video performance. An advanced hybrid mirrorless camera, the a7 IV has the resolution and AF performance that appeals to photographers along with robust 4K 60p video recording for filmmakers and content creators.33MP Exmor R BSI CMOS SensorNewly developed 33MP Exmor R BSI CMOS full-frame sensor features a back-illuminated design that promotes high clarity, low noise, and vivid color rendering. This design benefits working in low-light conditions and works in conjunction with a broad sensitivity range of ISO 100-51200. The sensor's design also achieves an impressive dynamic range of approximately 15 stops and files can be recorded in raw, JPEG, or the 10-bit HEIF format.
BIONZ XR ProcessorUsing the flagship-class BIONZ XR engine, high-speed image processing capabilities are available for fast continuous shooting, 4K video recording, and advanced AF tracking performance. The quick processing also helps to reduce rolling shutter and other motion distortions for clean rendering of moving subjects.

In terms of shooting speeds, the sensor and processor enable up to 10 fps shooting, using either the mechanical or electronic shutter and with AF/AE enabled. Also, the buffer permits recording up to 828 consecutive uncompressed raw + JPEG frames when using a CFexpress Type A card.
