I read on forum that the metabones RF to EF Speedbooster worked so I purchased one but I can Not get it to work at all. The iris cant be controlled at all? I even updated the latest firmware and still will not work. IDK what else to try? Am I doing something wrong? Should I send it back and wait for Canons Speedbooster to get delivered?
Anyone else been able to turn the F stops and get iris control.
Thx
