Metabones has updated its EF to NEX Smart Adapter II, allowing recent Canon lenses to autofocus on Sony E-mount cameras. As with most systems that attempt to use DSLR lenses on contrast-detection-based AF cameras, the focus speed is considerably lower than when used on their native cameras. However, despite not being able to use the hybrid-AF system from the NEX-5R or 6, Metabones claims performance is often better than Sony DSLR lenses being used with the original LA-EA1 adapter. The adapter costs $ 399, with existing Smart Adapter II owners able to upgrade for $ 50.
