Been going through the entirety of this forum to get caught up on the D500, today. So please indulge me, this "zombie response" to an old thread and for going so off topic.
I'm not going to buy a D5 just to get the memo functionality .... But it is a bad move to delete this feature from all second-tier models. D2-, D3-, D4-, D5-series all have this capability.
As does the antediluvian D100 natively when affixed to the Nikon OEM (can't attest to any third-party issue) MB-D100 battery grip. My understanding is the
much improved [sic] D70/D70s models never had an OEM grip and I know of no third-party product available to them that also allowed for WAV file recording; were that even possible without firmware support or a dicey software "hack". Indeed the omission of that feature alone (conversely the lack of a real, glass penta prism and the inclusion of "scene modes" being the more commonly stated reasons) factored greatly for some when choosing a D100 over the highly esteemed, newer cameras. I found the D100 "voice memo" feature especially efficacious for "PJ" work and when resolving postmortem
he said, they said challenges and similar surreptitiously produced "evidence".
I always made a point of addressing the nice police officers by name and badge number when it was demanded I turn off the camera -- "or else"!
