Hi, does anyone using metabones ef to e mount adapter. I have it on but I am not getting iris controls?

I have a cheap commlite EF to E. Working just fine. I did have to update my Sigma 18-35mm before it worked properly. Could only open up to F4 max before the lens update.

I do hope the roller can also be used to adjust iris and/or ISO later on.
