Product Details

Overview
Please note: Product may differ from image.
The Speed Booster ULTRA II is 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 stabilisation operation and communication status. A dedicated switch controls in-body image stabilisation (IBIS) on Sony cameras equipped with SteadyShot INSIDE.
Like all Metabones Speed Boosters, the Speed Booster ULTRA II is optimised to fully account for the camera’s filter stack located near the sensor surface. This is especially critical at the extremely large apertures made possible by Speed Booster technology. As a result of this careful optimisation, an enormous range of full-frame optics ranging from vintage film lenses to the latest digital designs will function flawlessly when adapted to Sony E-mount and Fuji Xmount DX format camera bodies.
