As far as wacky ideas go, this one actually seems pretty useful. Using a drone with a gimbal stabilised camera as a handheld rig isn’t a big secret. I know a few people who’ve done it, and I’ve tried it myself a couple of times, too. But they’ve all been fairly basic. Either they’re using a Phantom and simply holding the landing gear, or it’s a quickly put together DIY rig.
This, though, is pretty cool. It’s the Polar Pro Katana, and it turns your Mavic Pro into a handheld gimbal stabilised camera. This is the first time I’ve seen a ready-made solution, though. I wonder if it was possibly inspired the DJI Inspire 2 launch with a film which was shot by a drone using this exact technique.
