So, why, apart from price, should I go with the Calibri over the Movi and I mean this as a very genuine question, not seeking to stir any pots at all. Here is Freefly's take on why I should look at a Movi, taken off the Freefly Forum and written by Tabb who I believe is the head honcho at FF:
I wanted to give a quick list of features that we feel differentiate the MōVI from competitors. The below contains a lot of technical details about the various sub-systems on the MōVI. The sum of these systems is a robust, reliable and adaptable camera stabilizer that works in real world filming conditions. We have kept pretty tight lipped about what separates the MōVI from the rest of the pack until now. What this means for our customers is that they will have a system which will allow them to focus on shooting and shot design rather then endless hours of tweaking and gain adjustments. The MōVI does not just carry a camera like the Red EPIC; it does it easily. The MōVI can accelerate and slew a Red EPIC and ultra prime lens at 150 deg/sec, while other systems using sensor-less motor drives struggle. This is important as it directly relates to your ability to accurately and precisely command the camera. The MōVI design team features 10 engineers who are all at the top of their respective fields. These industry experts all working together to re-define camera movement.
I know a lot of people are desperate to believe that our competitors (I use the term loosely as the majority do not even have a product, just a rendering) are just as good as a MōVI at 1/3rd the cost. I am guessing as these systems are released and things shake out a bit and actual users get their hands on them, you will notice an overwhelming trend. The MōVI will continue to produce the stable shots it has become known for and you will see a lot of wobbly, vibrating footage from others.
