Sony a7/a6000 Intervalometer Hack

Update: It appears this entire project is no longer necessary. When I did this a few months ago, no one was offering an intervalometer for the Sony Multi-Terminal port. Now it appears there are some out there:

One weakness of the Sony a7/a7r/a7s and a6000 ecosystems is the lack of an intervalometer. There are a few options like TriggerTrap, but that and some others depend on a mobile phone, which seems unnecessarily complex and unreliable. There are a number of videos and articles demonstrating how to combine a Sony remote and an inexpensive intervalometer, but they don’t provide enough detail for those who don’t want to experiment. Here are the step-by-step instructions.

1. Get the parts.

I used a Sony RM-VPR1 wired remote and this intervalometer. You’ll also need some two-conductor narrow gauge wire (~22 gauge works), a soldering iron, and optionally a connector if you want to be able to use the remote without the intervalometer attached.

2. Disassemble the remote.

Four external screws and one that secures the circuit board to the case.

3. Cut a notch for the wire.

Use a small knife or drill to cut a notch into the rear of the remote’s case for the wire to pass through.

5. Cut the connector off of the intervalometer.

I left about 8″ of wire coming out of the intervalometer.

6. Use a connector to mate the intervalometer to the remote.

As shown above, the wire connected to point A should mate with the white wire coming out of the intervalometer. Point B should mate with the intervalometer’s yellow wire. (Polarity matters!) The intervalometer’s red wire is unused.DSC01932

I used a 3-conductor molex connector as shown above. Because I keep the two components connected all the time, I’ve secured the connector using cable ties as shown earlier.

7. Test!

Connect the remote to the camera. Both the remote and the intervalometer should be able to trigger the shutter. Don’t forget to enable the remote in the camera’s menus.

8. Reassemble the remote.

Route the wire through the remote as shown below. This will act as strain relief and won’t interfere with the operation of the remote’s buttons.

  1. Doug,
    Thanks for putting out this useful information in your blog. Not being adept at soldering or electrical skills, I opted to take the easy route and ordered the pre-configured online model. I plan to do some night sky shooting next spring and autumn out in the desert and this should help me have some fun!

    Much appreciated and send you my warmest wishes for the holidays.
