Conurus and Metabones have released a so-called Smart Adapter that allows Canon EF mount lenses to be mounted on Sony NEX camera bodies. Described as the first fruit of a strategic partnership between the two companies, the new Canon EF-to-NEX adapter allows electronic aperture control via the camera body - but no AF. This adapter is marketed under the Metabones brand name and may be ordered directly from conurus.com or from a Metabones distributor in Japan, the United Kingdom, Hong Kong or China for US$399.
