With the release of the latest Nikon DSLR bodies (D750/D5500/D7200) I was truly expecting Nikon to finally come up with a better main sensor AF system, either on-chip phase detection (which needs new sensor hardware in the form of specialized filters or "split pixels" like on Canons) or something akin to Panasonic's depth from defocus contrast detection (which is mostly more lines of code on the firmware, and thus might need new processor hardware in the form of faster chips). Nowadays, Nikon is the ONLY camera maker who relies solely on plain contrast detection for LV shooting and the only one without a solution to the hateful slowness and hunting that this type of focusing provides, especially when shooting video. Giving us focus peaking would also be very helpful. How much additional processing power does a camera needs to be able to provide focus peaking? Video is being pushed heavily as of late by Nikon's marketing people but they don't show true technical commitment on this regard.
And how about not having live histograms shown in LV stills mode on most bodies? That will be a wonderful tool to have while using old lenses, and that is something that Nikon has always been proud about, being able to use all Nikon F lenses from 1959 onwards. Live histograms and at least focus confirmation in LV would make using old Nikon glass oh so much more fun.
LV is not my go-to way of shooting with my Nikon DSLRs, mainly because how awful it is to use, but you have no other choice if you're shooting video, and there are a lot of instances when LV shooting stills is the only way to go. I think Nikon should put on more effort on this regards, at least to keep up with the competition.
