Metabones has announced an updated version of its Canon EF adapter for Sony NEX E-mount. The second version of the Smart Adapter will feature a screw-on Arca Swiss-style tripod mount, improved anti-reflection shieding and a mode that releases the aperture and stops image stabilization to reduce battery consumption. As with the original version, the Second Edition Smart Adapter offers aperture control, image stabilization and EXIF reporting compatibility with most EF and EF-S lenses. It will be available from August 2012 at the same $ 400 list price as the existing version.
