Metabones Canon EF to Micro Four Thirds T adapter (Black Matt) provides autofocus with an Optimum Balance of Accuracy, Speed, Consistency, and Reliability, Autofocus is supported subject to certain limitations (see table below for details). We are pleased to report that Panasonic Micro Four Thirds camera bodies are capable of autofocusing fast (large maximum aperture) lenses accurately. Although our first and foremost priority is accuracy, we are able to make great strides in autofocus speed as well.

Note 1: VC function of Tamron 28-300/3.5-6.3 XR Di VC model A20 may not operate, due to usually high current requirements.
Manual Focus Lens CompatibilitySome improperly-made M42 screw mount adapters may short the electronic contacts of the Speed Booster and cause damage to the Speed Booster and/or camera body.
Focus confirmation "chips" such as Dandelion are incompatible.
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 Speed Booster. They need to be modified before they can be safely used on Speed Booster. Check and make sure there are no rear protrusions from the adapter/lens combination before using on Speed Booster. Scratches and damages caused by rear protrusions on Speed Booster are not covered by warranty.
