Not say cannot but shooting the way I'm used to with Olympus IBIS, and without adopting strict technique, I need faster speed like wat Toth mentioned. I guess if i really wanted to, I could get into correct position and squeeze out a shot that may be sharp at slower speeds.
The omd em5 5 axis IS is really good. Used to own m4/3 system. Pity sony didn't use the 5 axis into the A7 due to heating and small body limitation.
