Do you find your images taken with Olympus 14-150mm lens on a Pen camera (E-PL2 in my case) have a little blur? I found that even at good shutter speeds, e.g. 1/800s I get a little blur (static objects) when viewed at 100% even with IBIS on. It's usually the case at longer FL. How does this lens work out for you, any tricks to share?
