IBIS cannot stop subject movement - so bad argument

Only in your mind. IBIS helps in most cases, and 5 axis IBIS helps even more. That is why Sony and Panasonic will adapt it.

How can IBIS prevent subject movement blur? 'Only in your mind'? My mind boggles!

BTW I overstated since the E-P3 had already 2 stop of IBIS, so in one generation only we earned two stops.

Add 2 stops of SNR, and we have *4* stops more available. No fast lens full open is going to give you that, especially not at full resolution.

Of course this doesn't mean that you cannot use fast lenses at full aperture, but there will definitely be less of a need.

Do you spend all your time studying specs or do you sometimes go out and take pictures? You might work out how this stuff actually works in doing what it was designed to do.
