Canon EF lens to Sony NEX Smart Adaptor launched
New Smart Adaptor to offer electronic aperture control of Canon lenses on Sony NEX cameras

Sino-Japanese lens adaptor manufacturer Metabones has teamed up with Vancouver-based lens modification specialist Conurus to create a new range of 'Smart Adaptors'

The first product in this series is billed as "the world's first smart adaptor for attaching Canon EF lenses to the Sony NEX's E-mount".

No autofocus

As with many third-party NEX adaptors, this Smart Adaptor isn't so intelligent when it comes to autofocus – it's manual focus only.

The development teams have only tested the adaptor's compatibility with the Sony NEX-3, NEX-5 and NEX-VG10E camcorder, too.

The Canon EF lens to Sony NEX Smart Adaptor features a Wide Open (WO) button that, once pressed, opens up the aperture to its widest setting. The default setting is for the lens to be stopped down to the shooting aperture in order to give an accurate measure of depth of field during live view shooting, although this can potentially make manual focusing harder.

The new adaptor costs $399 and can be ordered directly from Conurus. http://conurus.com/sony Nikon, Sony A mount and Micro Four Thirds Smart Adaptors are expected to follow.
