Sony's full-frame workhorse mirrorless camera connects to external recorders through a Micro HDMI (Type D) port — the small, fragile plug that needs a locking cage clamp for serious video work. A SuperSpeed USB 3.2 Gen 1 Type-C terminal handles fast tethering and in-camera charging, while a separate Multi/Micro USB 2.0 terminal supports legacy remotes and accessories. Dedicated 3.5mm microphone and headphone jacks let you record and monitor audio at once. Dual SD slots add storage flexibility, but only the top slot runs at faster UHS-II speeds.
