Sony bought 11% of Olympus for ¥50bn, the alliance will see the two companies set up a joint venture in medical technologies which they expect will capture 20% market share of a ¥1tn market by 2020. Sony will own 51% of the JV.
The two companies are also expected to collaborate on consumer technology, with Sony providing image sensors for Olympus cameras (the OMD-EM5 already uses a Sony designed and made sensor) and Olympus providing lenses and mirror cells for Sony's cameras. Yes, this means NEX is getting Zuiko lenses, which in itself is probably worth the ¥50bn for Sony.
The background to this is that Olympus had a major scandal where it was found that their directors were paying the Yakuza to keep news of investment losses out of the papers and away from the regulators. Olympus had a to pay a huge fine and declare the accrued losses last year. This meant their operating capital was reduced to just ¥50bn, by allowing Sony to buy 11% of the company they will double their operating capital and shore up the business.
For Sony, this is the second JV they have announced this year with Japanese companies, after the expensive disaster that was S-LCD with a non Japanese company, Sony seems to have realised that sticking with Japanese companies is probably best. What comes of this is unknown at this point. The investment is primarily for medical technology, 4k and 3d endoscopes are mentioned specifically, and for consumers cameras on both sides are mentioned. It also says that Sony will eventually buy up the whole JV just as they have done with Sony Ericsson, but it won't be for a long time. Essentially this is Sony buying their way into a ¥1tn per year market for just ¥50bn while getting a few side benefits such as Zuiko lenses on E-Mount.
