While I suspect only reason is very likely overstating the case, it does seem to me DFD has been and will continue to be a shrewd investment on Panasonic's part for this reason.DFD is the only reason why panny is still in MFT business.
While adoption of DFD is unique to Panasonic within the ILC industry it's a widely used algorithm in other areas. The only thing stopping Olympus from using depth from defocus has been Olympus. A corollary is JIP's likely purchased a portfolio of lenses whose focus groups and motors probably aren't optimized for DFD. Whereas Panasonic's been designing for it since adopting m43. So far as I know, Olympus does remain unique for having cross-type OSPDAF but it seems unclear if Olympus's longstanding 121-point array retains an advantage over DPAF or the dense arrays of recent Sony, Nikon, and Fuji iterations.True progress and way to fix the problem, IF IT'S EVEN DOABLE, is for Panasonic to give access and incorporate DFD into Olympus cameras and lenses
Personally, this leaves me unsure where JIP might go for AF sensing. From an industry consolidation perspective I also don't know that quasi-merging between JIP and Panasonic is more probable or more necessary than other possibilities. Given past behavior of most ILC manufacturers, whatever does emerge may be more culturally or politically aligned than driven by business or engineering concerns.
