Does anyone know if this lens can be used with m/43. I'm looking for something wider than my Oly 14-42 to go on my EP-2. I would be thinking of buying a Canon fit since I have an EF adapter. That way I could use the lens on both the EP-2 and my Canon DSLR. The appeal of this lens is the F2.8 wide open, so important for my night shots. Dave T.
