If you’re having trouble using USB with your Sony a7R III (ILCE-7RM3), here are some steps you can try:
Check USB Connection Settings:
1, Go to the camera’s menu.
2. Navigate to Network and select Ctrl w/ Smartphone.
3. Choose Off.
Then, go to Setup and adjust the USB Connection setting according to your needs:
Auto: Automatically establishes a Mass Storage or MTP connection based on the connected computer or USB devices.
Mass Storage: Creates a Mass Storage connection.
MTP: Establishes an MTP connection.
PC Remote: Allows control of the camera from a computer using Imaging Edge software1.
Check USB cable and Ports.
Use the supplied USB cable or purchase a compatible, commercially available cable.
-
- If your camera has a USB Type-C terminal, you can transfer images faster if you use a USB 3.1 compatible USB Type-C cable.
- If your computer only has a USB Type-C port, a USB conversion adapter is required.
- A gap will remain between the camera’s USB terminal and the USB cable once inserted.
- If the computer doesn’t recognize the camera even after performing the operations above, check the following:
- If the computer and the camera are connected via a USB hub, connect the USB cable directly to the USB port of the computer.
- Connect the camera to a USB port on the computer that has already recognized a mouse or other device.
- Try to connect the camera to other USB ports on the computer.
Also, Firmware updates may improve this in the future.
