This was done on a tripod by a known camera tester.  It also depends on lens focal length, the test
done was with a 200mm.

The solution is simple; Go mirrorless!

Is your main investment in lenses or DSLR body?

It doesn't make any difference. All my gear is Nikon/Nikon mount. If I
go mirrorless I would have to sell the lot.

In the meantime I want to take a vibration free shot with my camera on
a tripod. Do I now sell all my gear and buy a mirrorless of some kind,
or do I merely raise the mirror before I shoot? There is only one
sensible answer.

In your case, with your camera mounted on the tripod, raise the mirror, use 
LiveView, and manual focus with VR off, set the timer to release after 5-10 
seconds, and trigger the timer using a remote release.

....but if you really want an excuse for going mirrorless, there it is. ;-)

Remember, that with an adaptor you can still use your Nikkor glass, all 
manual, but you can use it.

If I was going mirrorless I would do as you did: start afresh with a
downsized camera and lenses to match.

As I have always said my switch to Fujifilm was initially due to Nikon being 
slow to deliver a replacement/update to the D300S. Once I had been exposed to 
the benefits of the Fujifilm X-System there has been no going back. If Nikon 
had released the D500 a few months earlier I might never have switched. Now I 
find myself with three Fujifim X-cameras, and 6 Fujinon lenses. That cash 
could just as easily have been spent on a D500, and some fresh Nikkor glass. 
Timing is everything, even in the release of cameras.

You could get a proper adapter and hot glue it to your mirror less 
databack... The Nikon Z mount is bound to have some OEM adapters, at 
least for more recent Nikkor glass.

If I did that I would not be able to use Z-mount lenses.

Most believe Nikon's new mirrorless will support (with an adapter) the old lenses.

With the E-M1 II in high res mode (80 MP) it's not sufficient to disable 
the mechanical shutter (i.e. use the electronic shutter). You need a 
wireless shutter release and you also have to disable the autofocus, 
because the AF motor movements in the lens generate vibrations.

Still no problem:

No flappy mirror - check!

Electronic shutter - check!

Wireless shutter release - check!

Manual focus with peak focusing - check!

As long as that pesky flapping mirror is not an issue the problem is solved. 
Unless of course you have chosen to stick with a DSLR.

Still no problem with my D750.

Select Mup (mirror up) - select.

No electronic shutter. See note below.

Wireless shutter release - check

Focus peaking (of a kind) - check.
See https://www.dpreview.com/forums/post/57292217

Heavy! Vibrate it if you can - check.

Note: I'm not keen on electronic shutters. They can lead to image
distortion with action shots and they are reputed to shorten the life
of the sensor.

Live View in action.

Noted.

Good.

Close, but not quite as effective, and useful as true focus peaking. However, 
for the type of shot that all of this procedure is intended for you would be 
using Live View, and it should be good enough.
>

Always possible.
Note, this discussion brought on us by Rich, and the geeky article he 
discovered, is going to be a minimal issue for those photographers with the 
appropriate knowledge, and skills regardless of the camera type in use. The 
results of any minimal vibration is going to need some serious pixel-peeking 
to detect.

Electronic shutters have their place, and provide an option over a mechanical 
shutter. However, as you have noted, when it comes to action shots where the 
shutter speed has been pushed, rolling shutter effect comes into play with 
all the unwanted distortion that brings. Though there are times those effects 
can be amusing. For the type of shot where the camera is tripod mounted, the 
subject is static, and vibration is to be minimized, the electronic shutter 
can be appreciated.

The solution is sensors with global shutters.

.... why would you need that if you are using the electronic shutter (no

Without an electronic shutter, there is no way to rid a camera of all vibration.
Modern Photography once bolted cameras to a concrete wall to try to eliminate it.  At some point,
long before an electronic shutter camera experiences it, a camera with mechanical shutter will blur
the image.  The only variable left with an electronic shutter shot is human hands holding a camera. 
Also, even on a tripod, any strong wind will induce some vibration which would impact any camera.

It also depends on the viewing angle of the lens and the number of
pixels in the image.

Doesn't have to be concrete. Can by anything, also sand or mud, as long

High frequency shake.  Does nothing for low-frequency ocean motion, vibration from engines, etc.

Actually the vibration from the engines is high frequency shake. The 
body movement is more of a low frequency thing.
