Metabones Announces New Mark IV Version Of Their Canon EF to Sony E Mount Adapter

By Anthony Thurston on July 13th 2014

Metabones is known for their amazing lens adapters for various camera systems, but probably most well known for their speed booster adapters. The company has just announced the latest version of their Canon EF to Sony E mount smart adapter.

The adapter allows you to connect your standard Canon EF lenses onto Sony E mount cameras like the Sony A7 series, and still have full control of the lens (Aperture, AF, Etc). Basically, the adapter takes the Sony signals and converts them to Canon signals, and acts as a pass through between the lens and the camera. It’s not perfect, but it works pretty well and is a great option for anyone heavily invested in Canon glass looking into the Sony system.

    Hi Anthony,

    Have you tested the AF performance comparing to the III version?, any gains on speed? the older version was to slow.

    “The adapter allows you to connect your standard Canon EF lenses onto Sony E mount cameras like the Sony a7 series, and still have full control of the lens (Aperture, AF, Etc).”

    So let me get this straight…If I connect an EF 24-105 f/4L IS to a Sony A7 using the Metabones, does this effectively increase the max aperture to f/2.8? Will there be any vignetting issues I have to worry about?

      No, this is not a speedbooster adapter, so your effective aperture will not be any different. As for vignetting, I have not used the adapter so I can’t comment on that.

    Pardon my ignorance here, but what exactly is different between this version and the previous version?

    I see the features bulleted above but what has been added since the last version?

      Improvements to the communication between lens and camera, as well as they fixed an issue in the previous version where under certain circumstances there would be reflections caused by the inside of the adapter.
