WTF DJI?! There's no option to mount the Osmo Action to a tripod out of the box?!  C'mon.  It seems I have to buy one of these for $10.  Shame on you.

If you don't already have one. I got a GoPro Hero (2018) from work that also didn't come with a tripod adapter, so I had to buy one to even use it. I didn't get much use out of that camera, but at least I have the tripod adapter for my new Osmo Action.

Hi, theface. Thanks for reaching out and posting your concern. The Osmo Action doesn't have a screw hole for the tripod but the Camera Frame can be mounted on a base or tripod.
