• Aug 2018: my initial thoughts on this new system

• announced August 2018 and the Z7 will be available late Sept 2018, while the Z6 will be available late Nov 2018
• thankfully, this system has been designed with a much wider lens mount diameter than the Sony or the Nikon F - 55mm inner diameter and a 16mm flange focal distance which means that theoretically it can accept lens down to f/0.65 (the Nikon F mount could only do AF lenses down to f/1.4, in reality, it is unlikely Nikon will be releasing a f/0.65 lens and if it did it would be very large and very expensive)
• optional Nikon FTZ Z-to-F mount lens adapter which costs $US250
  • Nikkor F lenses without VR will get 3 axis sensor based IS
  • Nikkor F lenses with VR will get 3 axis DUAL IS with the sensor providing the 3rd axis
  • Nikon mount Sigma lenses should function EXCEPT some interchangeable lenses shipped out before November 2013 that are not compatible with the latest DSLR cameras will not operate¹⁾
  • lenses that do not incorporate an AF drive motor will operate only in manual focus
