Metabones Smart Adapter IV and Metabones EF-E Speed Booster ULTRA 0.71x
Metabones will release Firmware Update 0.47 tomorrow to add support of Sony a7II FW 2.00 update and F/8 AF support with Canon EF 1.4x and 2x Extenders using Metabones Smart Adapter IV and Metabones EF-E Speed Booster ULTRA 0.71x.
I’m currently testing this update and I’ll post the download link with installation instructions as soon as it’s live on the Metabones website.
Please Note: You do not need to install version 0.47 if your adapter is already at version 0.46 and do not need Sony a7II or Canon EF Extender support.
