In September 2012, Sony announced that it would be giving Olympus $645 million in exchange for 11.5% of the company. The deal made Sony the single largest shareholder in Olympus, which was going through some tough times.
We’re now getting a better idea of what this new relationship means for the two camera makers. Olympus is reportedly handing all of its best tech (e.g. 5-axis stabilization, image processing engines, lens-making prowess) over to Sony for upcoming A- and E-mount cameras. Sony, on the other hand, will be providing Olympus with top notch sensors (rumored to be a completely new kind of advanced sensor starting in 2015).
