If this be the case, who has done this & your reasoning, examples & such please.
i use a panasonic gx1 body with the following lenses:
olympus 12/2.0 and 45/1.8
they all work flawlessly together.
because it was possible to pick the body and lenses that appealed to me most, and combine them without problem
obviously, none of the above have IS so there can't be any conflict there.
