I took my new Helix Jr. for a spin on a weekend getaway in Seattle. Overall it handled great. It took a bit of time and patience to balance the GH4. The front weight was a bit tricky, I had a meatabones speedbooster and an EF mount Tokina 11-16 up front. This will be a powerful tool in production. It does so much more than a stedicam and it does it better.
