Warch out for IS (Image Stabilisation).
It should be called CS. Camera Stabilisation.
It only works if you are trying to hold the camera still.
If you use it when panning, it actually makes your pix worse!
Also, at higher shutter speeds, the IS has insufficient time to operate. I use Olympus stuff and at speeds of 1/1000 sec. or better, IS is no help at all.
I've learned this info in the hardest possible way.
