When I purchased my first DSLR, an Olympus E-500, five years ago any thoughts of getting low noise, low light images above ISO 800 on a Four Thirds camera were just an impossible dream. Today, with the E-M5, that dream is reality! It's my cat, Thimble, taken hand-held at 1/30th of a second, f5.6, 150mm (300mm equivalent), ISO 12800 - with a Parkinson's tremor! A triumph, I think, for technology, both in terms of sensor performance in low light and the new 5 axis IBIS! Note: NO noise reduction or filtering applied, but + 0.7 exposure compensation set in camera.
