I wouldn’t say it’s revolutionary, at least not on the production side. It’s not like this camera is going to result in people making videos that couldn’t be made before the way say, technicolor was revolutionary.
What it is, is a really obvious idea that every other company should face palm for not having thought of sooner. It’s going to be revolutionary in terms of shopping. Every video person out there has a kit that that already has all of these features. But they get those features by purchasing several different pieces of equipment and combining them.
Camera, lenses, monitor, external recorder, gimbal, focus motor, etc. That’s at least 5, probably more, expensive pieces of equipment from different companies. You not only have to buy them all, but combine them together, configure them, make sure they are compatible, etc. Camera companies basically took this model of having separate pieces for granted, going so far as to make box cameras that were just a sensor in a box, expecting the customer to add every other piece of the puzzle on their own.
That’s because camera companies just make sensors and lenses, they don’t make gimbals and all those other accessories, and haven’t even tried to start doing so. They even go so far as to publicly suggest accessories like those that DJI makes. DJI meanwhile, everything they make that have a version that lets you use your own camera and a separate version that includes a camera. Just look at DJI Osmo, they have models where you attach a phone, and ones where you attach nothing.
Now, you could say that the fully integrated thing that camera companies make is the camcorder. True, but camcorders have really gone out of style for anything where they aren’t sitting on a tripod.
So yeah, if I was a pro video person I would absolutely be looking at the Ronin 4D. Saving all that time and hassle of combining various pieces and getting them to work smoothly together would be absolutely worth the price in terms of time saved if I was using the camera very frequently.
