Has anyone had success using the Metabones Speedbooster XL with the GH5? I have a Speedbooster with the latest firmware, but when I use Canon zoom lenses (24-105L, 100-400L) the GH5 locks up the moment I try to zoom in on something. It does work when the lens is on the widest setting. Wondering if there is something within the GH5 settings that I haven't set correctly or if Metabones needs to release a new firmware update. Metabones website says the Speedbooster XL supports the GH5.
