Sony Alpha a7 IV 2025
The 33MP full-frame Exmor R sensor and BIONZ XR processor capture 33-megapixel stills and 10-bit 4K 60p video, backed by 759-point phase-detection AF with real-time Eye AF. An included FE 24-105mm f/4 G OSS lens, extra battery, backpack, and 128GB SD card provide a fully equipped kit straight out of the box. This camera fits hybrid shooters needing high-resolution photos and detailed video in controlled settings, where image quality is critical but portability and in-body stabilization are not.
