Users of Metabones popular EF Smart Adapter Mark IV and EF Speed Booster ULTRA can now download a significant update for their adapters. Both EF-E and EF-M43 adapters receive updates.

The most significant change included in these firmware updates is for Metabones application (Windows or Mac), which now not only applies the firmware update to the adapter, but also allows control of several settings parameters, depending upon the adapter.

Metabones adapters have had options for 'green' or 'advanced' modes which, up to this update, had to be toggled via a button on the adapter. There was no way of knowing the mode for certain until actually connected to a camera. And even then, the user had to know which functions operated in which mode.

In the case of EF-E adapters, green mode has been determined to be the optimal mode for alpha-series mirrorless cameras, while advanced mode is preferable for the FS series camcorders. The application offers check box options to set the adapter to a specific mode when it detects either a mirrorless still camera or FS series camcorder.

An additional check box will allow the camera body itself to determine whether to use OIS (Optical Image Stabilization) or IBIS (Sony's 5-axis stabilization system on several mirrorless models). That selection defaults to 'off', since it still might be preferable to use camera menu settings to determine stabilization based upon the lens in use.

There is another option which allows the option of parking a lens infinity focus, where this is possible with the lens. This is applicable mostly to Canon STM lenses.

The EF-M43 included that same option to park lens in infinity focus, but more significantly, the ability to return a Panasonic camera to its iris-adjusting jog wheel state as well.

Metabones also notes several other fixes for both adapters, including autofocus accuracy and certain lens-specific improvements.

Metabones' web site has update versions for both Windows and Mac, as well as EF-E and EF-M43 adapters.
