Dual IS - optical IS synchronising with sensor-based IS to give unprecedented 5-6EV effectiveness
Video shot with the 300mm plus MC14 to show how amazing the IS is at 840mm field of view!
The Olympus 300mm f/4 compared to the Canon and Nikon 300mm f/2.8 - far smaller but it is 1 stop smaller but the field of view is actually 600mm.
That's one reason why Micro Four Thirds is far more fun and less burden!
It will be interesting to see how well the Olympus 300mm f/4 Pro lens competes with a Canon 7D II with Canon EF 400mm f/4L IS lens for birding - the Olympus will probably have faster AF for static subjects, face recognition AF, better image quality edge-to-edge, perhaps better IS, will be far less heavy and less expensive but maybe the Canon will do better C-AF tracking of birds?
