The mechanical shutter is needed, look here: https://nikongear.net/revival/index.php?topic=8075.735

Yes, I can't use the flash either in "silent mode".
But I think it is because the image processing and read out of image information from sensor if not fast enough. I guess in the future the mechanical shutter could be avoided.
With electronic shutter if may take 1/15 sec. or so to capture the image even if shutter speed is 1/1000 sec. So it is not "true realtime" capture with electronic shutter. 
I think it is like shutter speeds above flash sync speed with old focal plane shutters on film. It took let us say 1/250 sec. to expose image even if shutter speed was 1/1000 so I think same type of artifacts could be seen there with uneven exposure if light changes during exposure. Maybe not so pronounced as with digital.

Must be your eyes, Mike? I experienced no problems even with glasses on.

So, what about the Z system -- any viewing issues there?

I made a small comparation of sharpness between Z50 kit lens 16-50 set to 25mm at 6.3 (full aperture) and Voigtländer 25/4 snapsnot Skopar using 39mm adapter and Skopar set to aperture halfway between 5.6 and 8. 16 - 50 lens was with VR on at 1/160 and Skopar without VR (at 1/200) as Z50 has no IBIS and lens is just a normal prime without any VR. First image is 16-50 and second is Skopar. Third is 16-50 100% crop and forth is Skopar 100% crop. 100% crop is where focus point was. I was expecting the 16-50 to maybe be sharpest as it has VR and ED lens element and Skopar just an older lens from the film area but I think this test shows that Skopar has the "edge" (and good to know I am able to handhold this lens without VR and still get sharp images). It also benefits from being stopped down a bit and maybe both would be equal sharp at aperture 8. This is just some fun…..and not a very serious test :-)    …..but I have been confirmed again that 25/4 Skopar is a very fine lens. I am happy that adapters shows that they could be worth the investment.  On Z50 25mm is like 37-38 mm and a perfect "walking lens" for snapshots.

My Nikon S(RF)-mount Voigtländer 25/4 is a fine performer on the Z50 and the combination makes a neat package indeed.

On a tangential note: is there a reason for presenting your images this dark? It's hard to see sufficient detail.

I exposed to have the highlights "inside". A "habit" from slide time as I got a fear for blown out highlights when projecting slides :-)    …..but I have made a new set images where the dark part is lifted a bit and highlights still "inside". A graduated filter may have been useful.

Better indeed. However, a quick adjustment of the tonality curve is often required and easily done in the conversion software. Plus of course, getting the colour space setting correct for the given application. Otherwise the posted images can get rather flat, lifeless or muddy even with a colour-space aware browser. Set the space to sRGB when posting images is the safest approach.

My camera is set to sRGB. When I printed images I found this setting gave me a print closets to monitor. I started out with Adobe RGB many years ago but switched. "Real" pros probably use Adobe.
Light was a bit "flat" and a bit difficult. Still have to learn more about the camera. Maybe my monitor needs a calibration also.

Because I had great difficulty in seeing the full screen in the VF(D810, D800, D700, D300 and D200. Although I can’t recall such difficulties when I had a D70s!
I never had a D70, but started in digital with a D200.
I suspect the ability to see the entire VF image is somewhat dependent on whether the operator is nearsighted or farsighted, since the correcting lenses for each are widening or narrowing the field of view of the wearer, respectively. I'm farsighted (+2 diopter for infinity focus), and it is sometimes a struggle to see the entire view in a D800 or D610.  The D3 wasn't as bad. With the DX cams like D200 and D2Xs, there were zero issues, presumably due to the smaller apparent size of the DX finder image.

I'm near-sighted -3.5 to -4.25 within the digital camera epoch. No problems with the viewfinders of my Nikons despite the glasses. This continues with the Z models, no problems there either.

Today I´ve got weird behavior: the Z6 with the 24-70 4S could not focus to infinity, not even manually. Turning off the camera and taking out and in again the lens fixed the issue.
  Has anyone encounter the same problem? Did I activate a limiter of some kind or any other funtion by mistake?

I have experienced the same. A few times. Probably with the FTZ adapter. In my case(s) switching off the camera was sufficient.

Classic Win98-like situation. There are probably still firmware bugs present.

Paco: I assume you are NPS? If this behaviour repeats, file a bug report through NPS.

No Birna, I´m not. I´ll post a question about that on a different thread.
