Nikon’s been pretty quiet about new mirrorless camera developments since the launch of the Z6 and Z7. Other than the Z50, we’ve seen very little action at all on the Z mount system at all, except for the obvious lens expansion.
But now, according to Mirrorless Rumors, Nikon is getting ready to announce the Z5 next month. If the Z6 is analogous to the D750, the Z5 looks like it could be a continuation of the potentially-discontinued D600 series, set to compete with Canon’s EOS RP. But, with extras – like dual UHS-II SD card slots.
