Thank's for all your answers. My principle concern is about "means economy, i don't really know how to say in english, because i shoot all alone and i need to reason conviniently of what cam is more pratical to bring and use. This use is experimental, that's why i asked for the fps, because idlike to do animation and slowmotion as 24fps...I'm thinking about an electric one with a new portable battery... what do you think about "Du-all" ones?
