Camera Overview — Sony ILCE-9

The Sony Alpha 9 is a full-frame mirrorless camera built around a 24.2MP sensor paired with the BIONZ X image processor. It uses the Sony E lens mount and sits inside a magnesium alloy body with weather sealing, measuring 126.9 x 95.6 x 63mm and weighing 673g — a solid yet manageable package for professional use. The autofocus system combines phase detection and contrast detection with 693 focus points, and includes Eye Detection AF, Face Detection AF, and Animal Detection AF alongside subject tracking, making it well-suited for fast-moving or unpredictable subjects.

Burst shooting reaches 20fps, and the ISO range runs from 100 to 51200. In-body 5-axis image stabilization is built in. Video capabilities include 4K recording at up to 60fps with 10-bit color, and color profiles include S-Log2, S-Log3, and HLG.

The electronic viewfinder offers a 3686k-dot resolution at a 120fps refresh rate, while the rear display is a 3.0-inch tilting touchscreen LCD at 1440k dots. Connectivity covers Wi-Fi, Bluetooth, USB-C, Micro HDMI, and both 3.5mm headphone and microphone jacks. Battery life is rated at 480 shots using the NP-FZ100.

Storage uses SD, SDHC, and SDXC cards.
