google "global shutter".  The silent shutter on the D850, which uses electronic shutter, is not global, it's "rolling".  This will / may affect the x-sync.

I know lots of well-off casual photographers who have one lens and expensive cameras (D3X, D4, etc.).  And the stats, which I don't have at hand, suggest that the bulk of DSLR owners have only one ...

I just want built-in wifi that can be turned out without snapbridge. re: awl, having it built-in would be good - if one used the SB-5000.  Given the costs, few do so - I've switched over to Godox, ...

No.

That, and warrantee, and re-weatherproofing, etc.  It's not as simple as pop-out / pop-in.

The D850 has the same AF system as the D500. Since started to use the D500, I have not needed AF assist, because the D500 will focus in light so low you may have trouble composing.

That's very promising.  A 'final' test, if I may ask, is adjustability of WB.  It should be infinite as with a normal Raw.

A happy ending!  And much simpler than going to the camera store, although they would have tried the same thing (alternate cards).

Would you be able to try the Small and Medium Raw files?  Are they actually Raw?

Given that it's from a dealer, I'd take it there and watch as they do it.  Either you'll learn some unknown quirk or, or discover that your SD card is not quite right (and can buy a new one), or ...

By God you're right, it's an XQD.  Having the D3X on my desk, sometimes I mix the cards up. My point stands, nomenclature or not: ensure that the SD card is the only one in the camera.

To save you some wasted time, this won't work. You can either use HSS or HS (assuming HSS is active from live view / silent shutter, I've never tried it), but there is no physical way to get higher ...

Try removing the CF card - making the SD card the only one in the camera. If this does it (you appear to be doing everything else right), I will take my winnings in a simple "thanks" ;)

You don't need to update to 1.12 first.  I just did an update from and earlier version directly to 1.13.

No. You need to add the WR-R10 in a WR-A10 adapter. That gets you RF CLS, controlled by the camera with up to five groups. Or, you could continue with IR CLS, using an SU-800, Debao SU-800, or ...

I have one of oly's adapters - works fine. https://adapting-camera.blogspot.ca/2015/08/the-v1-f1a-is-dead-long-live-v2-f1a.html Since Oly can't promote his own goods here.

Yes (not a guess): because it isn't a global shutter.

SnapBridge will only do shutter activation.

1) Thank you - I have a D500, and what it won't do is what I need - activate the WiFi without snapbridge. This would enable tethering and control from Camera Control Pro (Nikon's software), ...

I wish you had asked me what to ask before hand :0 ;)
