Sony NEX-5 Air Release

Sony's infrared remote does not work well outdoors or when the control is not facing the camera. And it cannot trigger bracketed or auto-HDR shots, and does not activate auto-focus. So I built a simple adapter to let a mechanical cable release push the shutter button.

Now I can operate the camera remotely in all shooting modes. When close to the camera I use a regular cable release. For longer distances I use a Kaiser air-bulb release. The air cylinder has a five inch cable extension that screws into the adapter.

On my pano pole, which can extend to 15 feet, a length of self-coiling nylon tubing connects the air bulb to the cylinder. The bulb is a sturdy rubber one with an inlet valve, sold as a dust blower, that works much better than the rather flimsy one that came with the air cylinder.
