I have used my old Sigma 105 macro,manual focus as its predates built in motor,just fitted the Sigma 50-500 to the V2, its in the house but it focuses and no lens error message,we have no decent light forecast at the moment but will give it a go when we get some.
Just add i didn't try it @ f6.3,waiting for decent light for that.
