Of course there are pictures that "can't" be taken in the same exact way with MFT as with FF or medium format or full format etc, there will always be differences. Stating the obvious because you feel the need is just silly. Like I said, I only question your need to remark upon something like that, not the actual fact that it may be so.
Well, the problem is that every once in a while when there is a great new camera on the market, someone gets a little carried away in making exuberant statements about it, and if this kind of disease runs unchecked in some isolationist thread like this, then people start repeating it so often to each other than soon it takes on its own new internet truth and starts spreading like the plague. Pretty soon we would be hearing statements in various forums to the effect that the OM-D has beaten all FF cameras in IQ based on some tests done by an expert, and FF is dead, and other such nonsense.
Better to add a dose of perspective before it is too late.
