A recent firmware update to Metabones MFT-EF and some E-EF adapters includes smooth iris support for newer Canon and Tamron lenses, as well as other fixes and tweaks.

Metabones has updated firmware for its MFT-EF and certain E-EF adapters.

MFT-EF Update

The MFT-EF update includes the following new features and fixes:

Support for smooth iris in recent Canon and Tamron lenses.

Turns off OIS on Panasonic cameras when releasing shutter button if AF+MF is toggled on in camera

Fixes issues with Tamron 28-70 f/2.8 lens with Panasonic cameras. Other fixes include iris issues with older Olympus E-M1 cameras, as well as focus parking with several older Canon lenses.

E-EF Update

The E-EF update is applicable for Metabones Mark IV and SpeedBooster Ultra models.

It applies the following changes and fixes to these adapters:

On A7 and 6300 cameras, the wide open button on the adapter now activates the A7 and A6300 customizable Focus Hold function.

The Adapter now defaults to 'Advanced' rather than 'Green' mode. Metabones notes as an aside that A6300/A7RII/A7SII users prefer Green mode over advanced mode. Video users prefer Advanced mode over Green mode.

DMF, Eye-AF and fast CDAF is now supported on all E-mount cameras.

Smooth iris is supported on Canon and Tamron lenses.

Focus parking feature on older Canon lenses is fixed, as well as improvement in PDAF for Canon 50/1.4 lens.

Certain image utilities (not Sony) can display a descriptive lens name with EXIF LensModel Tag.

The firmware update is available free at www.metabones.com.
