Kipon, a China-based photography accessories maker, has announced that it has developed two electronic adapters (EOS-NEX and EOS-m4/3) that allow users to mount Canon EF lenses on Sony Alpha NEX and Micro Four Thirds-based camera bodies. It’s unknown if they permit autofocus control, but if they do, they would be the first adapters that allow full electronic communication between Micro Four Thirds and NEX bodies and non-system lenses (in this case, Canon EF lenses) for aperture and AF control.
Currently, Kipon is already selling non-electronic versions of the adapters on eBay.
While this may entice MFT and NEX mirrorless camera owners to try out Canon EF lenses, it’s unlikely that existing Canon EOS users would pick up a MFT and NEX body, now that the Canon EOS M mirrorless system camera is announced. Canon also offers an optional EF-EOS M mount adapter for those who wish to use their Canon EF and EF-S lenses on the EOS M.
Pricing and availability information of Kipon's new electronic adapters are unavailable at the moment.
