Regarding the D500 ... now only if no dust issues arise, or if they do Nikon doesn't take the first response in deny first, wait until China bans, and then admits awareness of an issue.
I am not a Nikon camera hater. I started using Nikon cameras in ~1985. Only when the D600 fiasco hit and how the company mishandled the problem did I walk away and buy a Canon. At the time of the D600/610 I was actually considering a D800e, but instead went with a 5DmkIII.
And while I have not picked up any of my older Nikon DSLR bodies (non-FF, EOL, disposable) I kept a very nice lens that does pretty damn good macro, which I have not yet found an equivalent in Canon. Maybe this is me thinking one day I might return to the Nikon fold. I'm such a polygamous.
