  • ¬†Adds GH5 support.
  • An irreversible change will be made to the following products which limits the ability to downgrade to version 2.65 but not any further back, even if you have a copy of an older version of Metabones App: Canon EF-BMCC T Speed Booster Adapter (model number MB_SPEF-BMCC-BM1/MB_SPEF-BMCC-BT1), Canon EF-BMPCC T Speed Booster Adapter (model number MB_SPEF-BMPCC-BM1/MB_SPEF-BMPCC-BT1), Canon EF-Micro Four Thirds Speed Booster (model number MB_SPEF-M43-BM1), Canon EF-Micro Four Thirds Speed Booster S (model number MB_SPEF-M43-BM2) and Canon EF-Micro Four Thirds T Speed Booster XL 0.64x Adapter (model number MB_SPEF-M43-BT3).

  • Fixed blackout issue with A7S running Time Lapse application.
  • Fixed issue with certain full frame lenses misidentified as cropped lenses (but the reverse may still occur).
  • Auto iris, servo zoom, autofocus and custom function button support for CN-E 18-80 T4.4L lens (except Mark I/II/III and original Speed Booster).
