I've made a new (short) Steadicam video. This time with the Sony NEX-FS100 on a Steadicam Merlin.
Lens on the camera is the Sony 16mm F2.8 pancake lens with VCL-ECU1 Ultra Wide converter. I bought this lens specifically for the Steadicam, because of the auto iris and focus. You don't have to use the auto functions, but it's good to have them on board.

Hi Darren,

Nice video. I assume you used the arm & vest for this footage?

Thanks Jordan. No I didn't use the arm & vest for this video.
I've attached a picture of the setup I used.
