Overview

The Metabones Speed Booster Ultra 0.71x F-Mount to E-Mount Lens Adapter mounts F-Mount lenses on an E-Mount camera body. Its optical group compresses the image circle to 0.71x, which widens the field of view and adds one stop of light. An aperture ring on the adapter sets the diaphragm, which keeps a lens with no aperture ring of its own controllable. A tripod foot carries the weight of the lens instead of hanging it off the camera mount.

Manual Aperture Control

An aperture ring on the adapter sets the diaphragm, which is how a lens with no aperture ring of its own stays controllable.
