Canadian lens interface experts Conurus and Sino-Japanese adapter maker Metabones have created an electronic 'Smart adapter' for using Canon EF lenses on the Sony NEX's E-mount. The adapter is manual focus-only but allows control of aperture and the use of the image stabilization on Canon IS lenses. Full lens information, including focal length, aperture and lens IS is reported back to the camera for EXIF, allowing the use of all P,A,S and M modes. The adapter also features a 'Wide Open' button that opens the aperture up for fine focusing, with the lens otherwise stopped-down to the chosen aperture, giving accurate depth-of-field in live view. It will cost $399.

Press Release:

Vancouver, Canada, January 18, 2012 - Metabones forms a strategic partnership with Conurus of Vancouver, Canada to jointly develop, manufacture and market a new Smart Adapter(TM) series of products featuring electronic interfacing with the lens.

The partnership is shipping its first fruition of collaboration today, a Smart Adapter that integrates a Canon EF mount lens to a Sony NEX camera body. Electronic aperture is directly controlled by the camera body and all exposure modes are available. Image stabilization (if the Canon EF lens supports it) and EXIF are supported, but there is no autofocus. This new smart 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.

Metabones is known for mechanical design that is already significantly ahead of the competition, as can be seen with the Contax G lens adapters for Micro 4/3 and Sony NEX with ultra-wide focusing rings and smooth manual focus action, and the ALPA lens to Leica M adapter with rangefinder coupling. Now, incorporating leading-edge electronic technology from Canada brings forth a new breed of adapters that not only truly integrates the lens with the camera body but offers the best workmanship, accuracy and reliability as well.
