Has anyone else tried the Metabones Speedbooster and Canon 16-35 F4 lens?
When I change the aperture, the screen flashes and the aperture goes to F0 before going to the selected aperture. It seems like the iris is opening fully before going to the selected aperture setting.
It's worse when I'm going down from F16 to F2.8. I have to do it slowly.
I've checked it on the 7D and C300 and the lens works fine on them.
I'm thinking it's a Metabones issue?
