New member with basic questions about IBIS and OIS: Will a panny OIS kit zoom on an Oly body (such as an e-pl5) lose it's OIS or does it work with IBIS active? Do they function with a net gain or actually fight against each other (assuming the Oly powers the OIS at all)? Would the focal length need manual entry in menu for IBIS? Thanks! GREAT resource here. I wouldn't have committed to buying into mu-43 soon otherwise.
