I really need a wide lens been researching a ton, almost bought the Tokina 11-16. The only problem I found and correct me if im wrong was that the lens doesnt have a manual aperature control and you cannot change the aperature from the BMCC MFT version not even with the speedbooster. Bottom line how would you be able to change the aperature with this lens without putting it on a BMCC EF version? Please help! ^.^
