Drone photography just took a step forward with ProDrone's Ultimate Flying Platform line of mounts, which are reportedly the first ones capable of carrying a DSLR on a consumer drone. They're designed to work exclusively with the Byrd line of quadcopters.
By letting people use their own cameras, ProDrone anticipates recruiting new customers and opening up new frontiers in high-quality drone photography. The mounts will work on all Byrd models and are expected to start at under US$100 for the static mount, with pricing for the gimbaled mount yet to be announced.
The number of cameras that are presently compatible with the mount is relatively small, however ProDrone is actively seeking partnerships with major camera manufacturers, so it's probably just a matter of time before more cameras are fully integrated into the platform.
As of this time, Sony cameras (DSC-RX100M4, ILCE6000, a7RII) and the Ricoh GR2 are fully operational with the Ultimate Flying Platform. The system is also available with limited operations for the Panasonic GH4, Blackmagic Micro Cinema Camera BMD and the Canon 5DIII.
ProDrone says that full integration will be available for all these cameras (and hopefully others) by Q2 2016.
