Your Canon EF lenses will now work when using the Metabones Speedbooster adapter
Metabones Firmware Update 2.7 - Post updated January 2018: If you already used the Panasonic GH4 with a Metabones Speedbooster to use all your lovely Canon lenses with, you know just how great this can be. Especially for video in my case.
The image quality from the GH4 with Canon glass is exceptional.
When I bought the new Panasonic GH5, I was blown away by the 4K 60p and 4K 25p 10-bit 4:2:2 quality. Therefore, I was looking forward to adding my Canon lenses.
You may have read that the Metabones Speedbooster Canon EF to M43 wouldn't work properly when attached to the new GH5. The output would be fine when at the lens's shortest focal length (16mm of the 16-35mm 2.8 L for example) but when you zoomed in, the screen would go blank.
I noticed that it would still record ok but that is useless if you cannot see what you are doing. The workaround in some cases was to push in the aperture button of the Speedbooster when attaching the lens. Then press it again to activate once the lens was mounted.
After speaking with Metabones about this, I got an email this morning with news of the firmware update fix. I have now updated and am happy to report that all is well in Metabones/Canon/GH5 land!
