An Easy Way to Fix the Annoying GH5/Metabones Speed Booster Freezing

Some GH5 users who have been using the Canon EF to Micro 4/3 Metabones Speed Booster XL x0.64 adapter in conjunction with the Sigma 18-35mm f/1.8 Art lens (along with some other third-party AF lenses) have been constantly reporting about an annoying freezing display issue that occurs when zooming in with the lens.

As you already know, the adapter allows a full-frame Canon EF-mount lens to be mounted onto a Micro Four Thirds camera while maximizing the apparent angle of view alongside increasing the effective aperture range with a 1.3 stop.

Fortunately, YCImaging has come up with a feasible solution that seems to successfully tackle the problem in a few easy steps. So, if you are eager to see the workaround, just make sure you don’t skip a second of the video below.

To resolve the problem, you have to turn off the camera once the freezing occurs. Then press and hold the aperture button on the left-hand side of Speed Booster XL adapter and turn on the camera again. Now, you should be able to zoom in or zoom out with your Sigma lens flawlessly.

Furthermore, to enable the aperture control, you simply need to press the aperture button on the Speed Booster once again. Even though this workflow isn’t the perfect solution, it’s still a viable workaround for the moment. If you do own the Speed Booster S adapter, however, you won’t be able to apply this trick due to the lack of aperture button on the side.

In addition, those of you who might be experiencing a black screen with the Sigma 18-35mm lens and Metabones 0.64XL, you may also try to update the Metabones Speed Booster firmware to 2.6. The latter might also fix the issue with the possible freezing on certain occasions.

Last but not least, it’s recommended to turn off the built-in image stabilization of the GH5 when using the Metabones Speed Booster since there is a potential risk to see the edge of the adapter’s image circle within your frame when the sensor moves due to the similarities in size with the GH5 sensor itself.

In the meantime, it has been reported that Metabones are aware of the “freezing” issue and they’re currently working on it. Supposedly, the bug will be fixed through an imminent firmware update.
