I have to be honest here, I’m actually starting to get a little excited about the idea of a Nikon mirrorless camera. I know I probably shouldn’t. I know it’ll be lots of hype and when it finally arrives I’ll be disappointed. But, still, the more little bits of information about it come out, the closer I get to certain that I will want one. And this latest development just brings me that bit closer. NikonEye are reporting on two new patents Nikon have published describing a new autofocus system. It combines dual pixel AF technology similar to Canon, as well as “time of flight” tech similar to new Sony sensors. The new autofocus system appears to be destined for the new mirrorless system.
There’s no link to the actual patents on NikonEye, but there is a google translated section.
So, essentially it seems that it uses the dual pixel data in order to build up some kind of depth map and determine just how far away the subject is. Something akin to how the iPhone’s dual cameras are able to build up a depth map in order to simulate a shallower depth of field. It has a set part which sets up the range which detects a focusing state from the information about the exit pupil of the aforementioned imaging optical system, and the information about the aforementioned pixel for focus detection, and a transmission section which transmits the information about the aforementioned range set up by the aforementioned
Given how badly video autofocus works for Nikon’s DSLRs, it’s nice to see they’re taking it a bit more seriously with a mirrorless camera. Hopefully, eventually, this tech will translate over for those who prefer the DSLR form factor.
The only thing I need Nikon to confirm now is that it’ll have a flippy out (like the D5600) and not flippy half-up (like the D750) LCD screen and I’m sold. [via Mirrorless Rumors]
