An all-arounder that pushes beyond basic the Sony Alpha 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.

The newly developed 33MP Exmor R CMOS sensor pairs with the BIONZ XR processor from the Alpha 1 to achieve quick shooting up to 10 fps and 4K 60p video recording along with broad sensitivity up to ISO 51200 and a wide 15+ stop dynamic range. Beyond image quality the sensor and processor also contribute to an advanced AI-based AF system that supports Real-time Eye AF and Real-time Tracking for intuitive AF control and subject tracking.

This fourth-generation of the a7 camera also sports an updated body design that houses a higher resolution 3.68m-dot EVF vari-angle touchscreen LCD and dual memory card slots including one dual CFexpress Type A/SD UHS-II slot. Connectivity and streaming is also a key attribute of this camera and it supports a simple plug-and-play design for live streaming directly from the camera when connected to a computer via USB.

Sensor and Processor
33MP Exmor R BSI CMOS Sensor
Newly developed 33MP Exmor R 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 Processor
Using 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.

Advanced External Flash Control
Suiting working with flash while photographing fast-moving subjects P-TTL flash metering is possible in between each exposure when working with lo mid or even hi-speed continuous shooting modes. This helps to maintain stable illumination if making low-light bursts and greatly benefits working in changing light or low-light conditions. The updated flash control system also helps to reduce flash trigger lag uses the camera’s AWB information for natural color rendering and supports adjusting select flash and transmitter units directly from the camera’s interface.
