ABOUT THIS DOWNLOAD

  • Name: Firmware update V0.41 for EF-E Smart AdapterTM MARK IV
  • Release date: 1 Jun 2015
  • Benefits and improvements:
    • User may choose between lens OIS and IBIS using the lens’ IS switch (except for some Tamron lenses). If the lens’ IS switch is ON, lens OIS is used and IBIS is turned off automatically.

    • Added autofocus support for some legacy lenses on A7 series
    • Eliminated iris flicker when opening up the iris from a slower aperture to a faster aperture in Green mode on FS series, NEX-VG series and A7 series in movie mode.
    • Eliminated iris tick noise while zooming a variable aperture zoom lens in Green mode

Canon EF Lens to Micro Four Thirds T Speed Booster XL 0.64x

Metabones updated another adapter and this one is mind blowing. The new Canon EF Lens to Micro Four Thirds T Speed Booster XL 0.64x basically turns the GH4 into a APS-C or S35 camera. It reduces the full-frame crop factor of the Panasonic GH4 from 2.0x to 1.28x transforming these cameras into APS-H format. Crazy!

    I have two a7s for weddings, but am tempted by this. A second-hand gh4 and one of these new MFT speedboosters would be a very cost-effective way to shoot 4k video from the back of the room as high-quality wide angle backup view of the main table/action using my existent Canon glass. Very, very interested in this one! Thanks for the update Eric.

    Holy cow…. this makes me want to sell my native m43 lenses… so f4 lenses become what? 2.2? 2.4? My mind is blown…
