Well, Alexa is way to expensive for my budget. At the moment, Raven is most interesting because of size and slowmotion capabilities. About Sony fs7, actually i haven't thought of that one. Though it seems to be quite big, similar to ursa mini. Also, its the problem with lenses. I have two pair of Samyang EF lenses wich i can use with either raven or ursa.
Though i dont think Raven price has to be that big. The only thing i need to buy is brain + jetpack as it can be powered through the ronin and controlled through wifi and a 3rd party monitor.
@bzpopBM micro cinema camera is really interesting indeed! btw here is a showreel of most of the things iv done
