I wrote Olympus about the no IBIS with E-M5 and legacy lenses. Just got a mail from them :-( "Thank you for your E-mail regarding IBIS. We are sorry to inform you that we are unable to guarantee the operation with non-native adapted lenses in exception of genuine products. However, we are constantly making efforts to improve our products. We are always grateful for customers' opinion. Thank you. Best regard, T.Katagiri Customer Support Center OLYMPUS IMAGING CORP.
