Sony A7 IV vs FX3

In October 2021, Sony launched the Alpha 7 IV, a full-format, 33-megapixel mirrorless camera. This model, the successor to the acclaimed A7 III, brings a number of improvements. At the core of the a7 IV is a new 33MP sensor and the BIONZ XR processor, enabling 4K UHD recording at 60 fps (with APS-C cropping in 60p) and Full HD recording at 120 fps. The ISO range extends from 100 to 51,200, with an extendable maximum of 102,400, offering exceptional low-light performance.

The Alpha 7 IV features 5-axis stabilization, protection against the effects of temperature and humidity, and an impressive battery life of up to 670 photos. The camera features two memory card slots, one SD (UHS-II) and one CF Express Type A, along with comprehensive connectivity options, including a USB-C port. The camera's hybrid autofocus system, comprising 759 focus points across 93% of the sensor area, and its ability to track eyes and faces (in both photo and video modes) represent particularly powerful features. The 3.69 million-dot OLED viewfinder and enhanced touchscreen provide optimal ergonomics for all types of shooting.

The Alpha 7 IV has been designed with the intermediate and expert photographer in mind. It is a versatile camera, ideal for portrait, landscape and video shooting. Although the A7 IV is more expensive, it represents a significant advance on the A7 III with its enhanced video features and sophisticated autofocus. Nevertheless, the A7 III remains an excellent alternative for those seeking unbeatable value for money.

Available in March 2021, the Sony FX3 is a dedicated video camera that brings together Sony's Cinema and Alpha lines. With its 12.1 MP full frame sensor and BIONZ XR processor, it offers outstanding performance while remaining compact and lightweight (715g). Designed for discerning videographers, it offers advanced features such as 4K UHD recording at 120fps and 1080p recording at 240fps for smooth shooting and superb slow-motion capture.

The FX3 incorporates cutting-edge technology, including fast hybrid autofocus using AI-based algorithms to ensure precise tracking of moving subjects. The body also incorporates an image stabilisation system and offers the ability to adjust user LUTs for greater flexibility in post-production. Dual memory card slots accept one SD UHS-II card and one CFexpress type A card for efficient file management (including backup).

In terms of ergonomics, the Sony FX3 has been designed with multiple ¼""-20 mounting points directly on the body, allowing you to attach a wide range of accessories. The detachable handle with XLR inputs enables professional audio recording, making this body ideal for content creators on the move. With its many features, the Sony FX3 is positioned as an interesting choice for those who want to produce high quality video with great efficiency, prioritising the video aspect over the photo side.
