Metabones Canon EF Lens to Micro Four Thirds Speed Booster Now Shipping
It’s finally here! Metabones has released the EF to Micro Four Thirds Speed Booster. Yes I just ordered one and I sure hope it wont take to long to deliver. We have been waiting for a long time for an adapter to use Canon EF lenses on the Panasonic GH series cameras and now with an added bonus of the Speed Booster we have it!. Also very impressive is the adapter supports image stabilization and gets power direct from the camera. No external power supply needed. Very cool!It’s hard to type while I’m jumping for joy! Ha!
The adapter is expensive at $600 plus shipping. However it opens up all my Canon lenses and EF mount ones too. Below is a full description of the adapter. Missing from the list is the Sigma ART lenses. That will be the first ones I test when it arrives.
Micro Four Thirds has a 2x crop factor compared to full frame so this adapter will make your full frame glass closer to s35. (Makes lens 0.71x wider.) Not full frame on the GH4. Canon APS-C lenses have a EF-S mount and are not compatible.
I’m not expecting the auto focus to be as good as a native lens is. With the Canon EF To NEX It’s very slow and not accurate. For stills I need AF to work. I can live without it for filming. I have the adapter for my A7s and it’s disappointing. Hopefully it wont have the communication issues that version does. Still even if it isn’t perfect it’s a much needed tool.

Note:
- Requires lenses supporting distance information.
- A third party zoom lens may need to be registered with the Speed Booster/Smart Adapter first in order to detect its maximum aperture.
- This Smart Adapter is designed to cover an 17.3mm x 13mm sensor.
- Some improperly-made M42 screw mount adapters may short the electronic contacts of the Smart Adapter and cause damage to the Smart Adapter and/or camera body.
- Many manual focus lenses (e.g. OM 28/2.8, OM 50/1.8, Leica R 15/3.5) have rear protrusions (spikes, levers, other appendages) which would damage the optics and/or housing of Smart Adapter. They need to be modified before they can be safely used on Smart Adapter. Check and make sure there are no rear protrusions from the adapter/lens combination before using on Smart Adapter. Scratches and damages caused by rear protrusions on Smart Adapter are not covered by warranty.
- For those passive (without electronic pin or without power supply from the camcorder) MFT camcorders, this Smart Adapter can also be powered by external third-party 5 Volt MicroUSB power supply*.
* ) third-party 5 Volt MicroUSB power supply is not provided in the box. The compability of 3rd party power supply can’t be guaranteed.
