Olympus incorporated 5 axis image stabilization into their OM-D E-M5 mirrorless camera back in 2012. The key feature of this is that the stabilization is carried out by moving te sensor, rather than in the lens. Micro 4/3rds Photography has attached a LUMIX GH4 with a Samyang 7.5mm lens to the front of an OM-D EM5 II camera (without a lens) and recorded the actual movement of the sensor correcting camera movements. For those that doubt the effectiveness of Olympus’s stabilization, this would seem to suggest that it works pretty well!
