Metabones recently released a firmware update for all of their MFT (Micro Four Thirds) to Canon EF mount adapters. Version 1.7 of the firmware works with the original Speed Booster, S, and XL models. The update brings a very interesting element that has been missing from the bones world of adapters. If you're familiar with Metabones adapters on MFT systems like the Panasonic DMC-GH4, you know that autofocus has never been supported, making action photography a really hard thing to achieve. Now you don't have to worry about that as v1.7 brings the following to the table in the update:
- Autofocus for Panasonic cameras
- Fixed a camera-becoming-unresponsive issue after double-tapping on the touch screen of a Panasonic camera
- Fixed EF Extender recognition issue with EF70-200/2.8L IS II USM
The Speed Booster XL (the one I have) shipped with v1.5 and it work really well. But having autofocus is a whole new element of excitement.
The update process is very easy to follow as the Metabones update app pretty much takes you step-by-step to a successful update. Download the application HERE.
Keep in mind, it is recommended that you exit all applications on your Mac or Windows machine before beginning the update process. Specific to the XL Speed Booster, it requires an extra step where you hold down the manual aperture button to initialize the update process.
If you don't hold down the aperture button the Metabones application will remind you with the following warning message:
Ultimately, this is very exciting news and I'm stoked that it is now an option with the GH4 running Metabones. Making this system one hell of a killer option for videographers and photographers alike.
BIG NOTE: The autofocus function does not work when shooting in 4K 24p, 1080 24p, or any VFR (variable frame rate setting) for some reason. Bump it up to 30p or drop it down to 1080 (any frame rate except 24p and the VFR settings) and you've unlocked the autofocus capabilities.
Don't quite know why it doesn't work at 24p in 1080 or 4K or any of the VFR settings - if I'm missing something here, let me know in the comment section down below!
