The Sony NEX-5 is generally not supported for tethered remote shooting from a computer. Based on Sony’s supported-camera lists for Remote Camera Control / Imaging Edge, the NEX-5 is not one of the models that can be controlled this way.

So if your goal is to trigger frames for stop motion directly from a Mac or PC, this camera is not a good fit for true computer-controlled capture.

A practical alternative is to use a remote trigger instead, such as an IR remote, to fire the shutter without touching the camera. That can still work for stop motion, but it is different from full tethering because you won’t have complete camera control from the computer.
