Metabones is launching its fifth generation of speed boosters to commemorate its five year anniversary. This release consists of four new adaptors: EF to E CINE Smart Adapter™, EF to E CINE Speed Booster ULTRA, EF to E Smart Adapter V and EF to E Speed Booster ULTRA II. The EF to E CINE Smart Adapter™ and EF to E CINE Speed Booster ULTRA are aimed at Sony’s cinema line such as the new Sony FS7 II. The EF to E Smart Adapter V and EF to E Speed Booster ULTRA II target photographers and cinematographers who use the Sony a7 series. These new adaptors promise more robust features and superior usability than their predecessors.
According the Metabones Website:

All 4 new products are equipped with a rubber gasket to protect the E-mount connection from dust and moisture. To promote ease-of-use, an LED indicates the adapter’s operation mode, optical image stabilization operation and communication status. A dedicated switch controls in-body image stabilization (IBIS) on Sony cameras equipped with SteadyShot INSIDE.

These features not only keep pace Sony’s current cameras but they also position Metabones very well for the looming release of the next generation of Sony’s camera bodies. It will be interesting to see how other adaptor manufacturers keep pace. Metabones’ products aren’t cheap but, for those wanting more functionality than the simply mounting, they have have been generally viewed as the gold standard
