Sony A7 III (2018)

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.

Sony’s full-frame mirrorless with Micro HDMI, USB-C 3.2 Gen 1, dual 3.5mm audio jacks, and dual SD slots (one UHS-II).

Notes & Compatibility

Micro HDMI (Type D) is delicate — use a cage/clamp for video rigs. USB-C is USB 3.1 Gen 1 (= USB 3.2 Gen 1, 5 Gbps). Separate Multi/Micro USB 2.0 terminal for legacy remotes. Slot 2 also accepts Memory Stick PRO Duo (legacy, not modeled). Multi Interface Shoe and NP-FZ100 battery covered in prose, not cable ports.
