I recently purchased a Steadicam Aero 30 and had the chance to test it out with a Sony PMW-500, here's one of the shots I'm pleased with.
I had previously been practising with my Canon 5D which was challenging as I couldn't get a HDMI from the camera to the monitor. It took me a while to get used to balancing a heavier camera but it felt much better to use compared to a DSLR.
I'm still working on keeping my corners and horizon straight. Any other suggestions would be appreciated!
