Back in August, Sony released a driver program to let their cameras be used as webcams on Windows 10 and solve at least a small part of the webcam shortage that has been going on since the pandemic forced millions into remote work. It took a little extra time, but now there is also driver software available for Apple Mac computers.
Imaging Edge software works for most of Sony’s latest cameras, including the Alpha DSLR and mirrorless series dating back to the 5100, plus fifteen DSC-HX, RX and WX point-and-shoot models and the ZV-1.
To use it, you need a compatible camera (full list on the download link), a USB cable and MacOS 10.13 or later. It should be a real upgrade over any regular webcam, provided you can place your camera far enough away from your face to get it framed.
