HD Blackmagic Studio Camera Internal battery has been removed, allowing for a lower retail price and easier shipping! Based on user feedback, most customers doing live production use AC plug in power, so they have asked for a model without the battery. In addition to making the cameras more expensive, the large internal battery also made it difficult for customers to ship their cameras via air freight when they needed to take it on location for a shoot. With the battery now being removed from the camera, customers can ship them anywhere. The removal of the battery allows the camera to be sold at this new lower price.
