At this price you have to but questions where the catch is.
And yes, there is a catch if not several:
-The Battery life
-The Display
Shape / size
etc.
But most of these "errors" can be solved by accessories, the poor battery life, for example, with an external battery can Behen easily.
Really very difficult to see the display in bright sunlight which is can be replaced with the HDMI terminal on the camera through an external display or an electronic viewfinder.
Since the camera is quite small, but you can all accessories not easily attached to her so you need a rig or a Cage, which also falls into the money again.
What I want to say ultimately is that if you buy this camera, you can buy any camera set but rather "only" one sensor and one is needed the rest of equipment which itself drumrum build and needs to build its own setup. If you have this setup then (and if necessary even without) can extract this camera a really great "cinematic" image, you just have to know how to deal with it and has to edit the files later.
