I take my info about image stabilisation and coffe from my reliable source : opticallimits reviews

The built-in image stabilizer is good enough for 5 f-stops - and up to 8 f-stops when combined with in-camera IS. This is certainly appreciated when shooting macro because things can get pretty shaky at very close focus distances. Whether it's truly a 5/8 f-stop gain depends on your degree of coffee intake.
