Unless the diopter adjustment could accommodate the range necessary?

Even if the difference of the distances are within the range of diopter adjustment, it should be totally inconvenient if you have to re-adjust the diopter every time you switch between OVF and EVF.  The automatic adjustment in the ocular can make the pentaprism bigger and complicated.

by that reasoning then, it'd make more sense to add a translucent EVF screen on the same plane as the focusing matte, most likely after it along the optical path, ie. sandwiched between the matte and the prism.
It would then lose a small amount of light transmission in the OVF system having a clear/transparent LCD type screen in the way too.

Surely tho, if there as indeed a switch for an EVF, that the switch would also act on a refocusing mechanism to account for any focus discrepancies.
Alternatively the EVF LCD component could be made deliberately unfocused to take into account that focus distance issue, thereby making in focus at the ocular.

For them to remove the built in flash, the implication must surely be that the prism is probably going to be larger in some way.

Apparently it will just have a plain old OVF . . . according to the latest rumors.

No big innovations in this camera - just the same evolutionary feature/design changes one would expect.

Well, if that mirror goes up, how does it black out the pentaprism?

As it seems, Nikon is working on an adapter, to use lenses for mirrorless cameras on cameras with a mirror box, so I assume they also are developing mirrorless cameras:

I think the third mentioned patent there on nikonrumors is quite interesting about Another converter lens patent - probably for a fix lens camera. It is about a relay lens, which enables to use a lens, which would interfere with a mirror box, on a camera with a mirror box  .

I am very happy with an OVF.  Nikon has had almost 60 years to prefect it.  Meanwhile, we keep getting tidbits.  8fps+.

Visited Nikon Austria today

Their officials were talking about the D850. Findings:

10 fps (without battery pack)
together with fast AF this will be a sports capable camera with 46 Megapixels resolution
(appears to adapt something of the D500 concept for FX)
NOT compatible with MB-D12, there will be a new dedicated battery-pack
They expect the first samples to be available in October
Pricing will be about 1000 Euros above the D810 which will remain available in parallel

I see a tendency of Nikon to sacrifice the low-ISO dynamic range for the high-ISO performance and faster frame rate (data readout) on the newer models (D500/7500 compared to D7200 as well as D5 compared to D4s).  According to the comparison of the DR performances of D810 and D810A, they seem to know how to tune the sensor.

Hopefully they don't do that on D850 compared to D810.

Wolfgang, that last line is a bummer.  I thought maybe the D850 and D500 would work for Soccer.  The 46MP taking the place of a TC1.4 on the 300 f2.8.  Finally retire the D3S but the D3S is good enough when it comes to money. Have sold more gear (and still more to go) so will wait and see  :) .

Forgot to mention: D850 will use EN-EL15 batteries but there is a new version out now (the third one) the EN-EL15a. Nikon gave me three of them to replace my old 01 versions that do not fully support the D500

It will most interesting to see how the dynamic range performs, especially at slowest ISOs. Perhaps the D810 may remain the optimal solution for landscapes and closeups.

The leaked photos confirm similarities to the D500, in all this intrigue...
Hope a 3rd version of the  EN-EL15 will also work in the D500!

EN-EL15a is essentially the same as the "Li-ion20" version of EN-EL15 that addressed the compatibility issue of the first version (Li-ion05) with D500.  Then Nikon changed the model name to that with the suffix "a" and the color from darker gray to lighter gray to make the incompatible and compatible versions more discernible when they released D7500.  So, no worries.

As Akira said - dont worry
Successfully used a new EN-EL15a in my D500 today
First version was the 01 (not 05), followed by 20,
"new" EN-EL15a is still 20 but gray instead of black as been mentioned alrady

Now, that's bad news on the price, but good news the 810 will hang around.
