I saw this a few days ago on the m4/3 rumors site (thats where us Oly guys go). It is an interesting developement, The 4/3 sensor is an exact 2x crop factor. This gives the drone a much larger sensor and the ability to mount over 100 different lenses. Of course it will take a larger drone, but the new Oly pro lenses are right up there with Nikon's best.
