Much of this thread has concentrated on the specs of the Z7 and Z6, but can I look at it from a different angle. All camera manufacturers need to sell to survive. To whom will Nikon sell the Z7 and Z6? I have been a Canon person for many years originally, I guess, by accident. My first SLR after a Practika was a Canon. I have no idea now why it was not a Nikon. About 30 years later I went digital and got a Canon 10D as I could keep my EF lenses. I have ended up with a 5D3. Eventually the lure of a smaller, lighter system with more information in the viewfinder lead me to try a Fuji X-E1 with the 18-55 lens. It did not break the bank. The X–E1 eventually lead to a X-T1 and now an X-T2. I am delighted and take more images and have more fun with a camera and lenses that I am happy to take around with me in a much smaller bag that the 5D3. Mirrorless is for me.
Would I buy a Z7 or Z6? Very unlikely. Why? Too much cost for too little return now I am into mirrorless as many people I meet are.
Who will buy the Z7 and Z6? I guess that Nikon hopes to stem the number of people leaving for the likes of Sony, Fuji, and m4/3, by getting them to stay with Nikon when going mirrorless which seems an unstoppable development. But what about converts? Is the price too high given that such people will have to invest in glass as well unless adapters are made available. (I do not like the thought of an adapter as it means extra weight and size. I do not even like using a grip with extra batteries and prefer to just carry spare batteries in a little Think Tank battery holder.) Will those who have another system be tempted to spend a considerable sum of money to change to Nikon? As this is Nikon’s first serious foray into mirrorless, they cannot sell to Nikon upgraders from a less good mirrorless body, so that market sector does not exist to them.
All of this will also apply to Canon unless they introduce a camera with real competitive advantage. I do not know if the market will see the Z7 and Z6 as having sufficient competitive advantage. I hope for Nikon’s sake that people do.
Best wishes,
