New MB version 2.5 out
There is a new MB version out for the bold to try
Name: Firmware update V2.5 for for Canon EF to Micro Four Thirds Smart AdapterTM/Speed BoosterTM
Release date: 4 Nov 2016
Benefits and improvements:
Fixed IBIS support with Sigma 50-100/1.8 DC HSM Art 016 lens on Panasonic GX7, GX8 and GX80/85.
Olympus OM-D E-M1 PDAF improvements.
Option to park focus to infinity upon shutdown to shorten its length for storage. Some lenses may disregard this setting but never park focus, and most of these are internal focus lenses which do not require parking. STM lenses always observe the option setting.
Changing iris on Panasonic using the adapter's jog lever requires first pushing the jog lever inward to activate. There is a customizable option in Metabones App to get back the previous behaviour of activating jog lever iris control whenever the jog lever is pushed in, up, or down. In both case jog lever iris control terminates with the control relinquished to the camera body by pushing the lever inward.
Fixed an issue with some telephoto zoom lenses not being able to start up at maximum zoom position with EF Extender attached on Olympus cameras.
Fixed an AF inaccuracy problem on Panasonic Lumix DMC-GM1 with EF135/2L USM.
Fixed issue with Tamron VC USD where autofocus may occasionally become inoperative.
