It's no skin off my nose - just a warning to those who are considering buying the D500.
You can argue it anyway you want but not having a pop-up flash is more poor design and an attempt to make the camera appear more professional. Having a pop-up is not desperation! I shoot with a D800E with pop-up that is used infrequently, but when it's used, it is helpful. As I said, I have a full sized Nikon flash, but often, it is overkill. The pop-up is, dare I say, convenient, whether you are a pro or not.
Besides, it doesn't matter who the camera is marketed to, it's new and it's sexy and there are far more non-pros who will buy it - only to realize too late how useful a pop-up flash can be.
That's your opinion.
I don't think the designers wanted the D500 to "appear" more professional, but to
be more professional.
Pros use external flashes which they configure optimally. It is actually amateurs who use pop-up flashes ...
Which brings us to the another point: external flashes are not "overkill" if you adjust them to minimize the output.
Of course, we all have different shooting styles/needs, but for me, when I often need to go to Full Auto mode, and get a quick shot, the pop-up flash is nothing but an annoyance.
I would say the annoyance/useful factor of a pop-up flash is 100/1 for the way I shoot.
Even when I shoot nature photography, I rarely use flash.
I also believe the viewfinder has been enlarged, thanks to not having the pop-up flash.
I don't expect to convince you, if your own style of shooting prefers pop-up flashes; I just think it's incorrect to say that Nikon is wanting the D500 to "appear" professional ... I think, based on ALL of the wonderful, needed/desired specs that have been put on this camera, that even Ray Charles can see that Nikon's goal is to make the D500
for professionals (who don't need the bulk of the D5, but who want the same basic feature set).
