Autofocus issues rendering the lens useless

This lens is just useless in some environments (e.g. studio, indoor shooting with av. light) if you use an A7RII or A7SII. There is a focussing bug in the camera's firmware that makes the iris stay closed while you focus even if preview of settings is switched 'off'. Focussing with F8-11 is just impossible in dim light conditions. It takes an eternity to lock on and often fails. This makes this lens quite useless for any professional work. Sony really needs to adress this.
