Sony Alpha a7 IV 2025
The 33MP full-frame sensor and BIONZ XR engine enable 7K oversampled 4K 30p and full pixel readout 4K 60p 10-bit 4:2:2 video recording. AI-driven subject detection autofocus tracks eyes and faces reliably across stills and video, reinforcing the camera’s hybrid versatility. It best suits hybrid shooters and event photographers who need detailed 33MP images alongside high-quality oversampled 4K footage, but not for fast action or vlogging.
