The Debao works on a D850, but can't be controlled from the menu any more than a Nikon SU-800 can.

Oh. I'll just throw MGrue under the bus then ;) And wouldn't it be great if old threads had some highly-visual indicator, like colour codes on the dates?

Well, no. If the screws were pulled out they, or the female thread in the body, are stripped and will never again have the pull strength they had from the factory. The only fix is to Nikon, which ...

I, apparently incorrectly, assumed that reflections in eyes would be a stationary thing. Anyway, if you have a specific distance and aperture, AF Fine tune for that and carry on. I think you'll ...

It is! Your best bet is to focus with live view.

You may find that a wrist strap is helpful - I do. For example: https://www.bhphotovideo.com/c/product/838164-REG/Camdapter_00_0201_NATURAL_Pro_Strap_Natural.html

I'm not so sure this matters.  The analogy is the HiFi Audio era being swept away by MP3.  Most people couldn't hear the difference and didn't care anyway. Same with the difference between great ...

Write protect switches are one of the most common failure points for SD cards. Glad they aren't on XQDs.

Under "More Options" in someone's post, there is an "Ignore User" option - helpful in these cases.

Yes.  Much better image quality through improved ISO and overall sharpness, and as importantly, much better AF speed. You might rent one to see before committing - or buy a used one and, if you ...

That's entirely up to you. I have already addressed that with the cookies part of my response. From the last post on the first page (at least on my browser): " Thanks for your great responses.. My ...

Done.

Do it from a second browser for your second camera.  Or dump the cookies from your regular browser.

Ken has it right.  It's recommended, and it's how I do it with good results.

Canon is over-thinking it.  11 is all anyone needs. More seriously, the number of connections depends on the communications type (serial, parallel, or what have you) and could be as few as 3 - ...

Attached to your 105, extension tubes (I like the Kenko version) or some combination of Nikon 5T and 6T closeup lenses. Depends on how much you can to exceed 1:1 and how much working distance you ...

I've just discovered that he is pushing the ether theory, discredited in 1887 and crushed in the 1920's. Wow.

Not yet. My card failures have been CF, which I used for more years.  I've used XQD only since the D500 came out (I was an early adopter).

real-life early reports are 4-5 times that.  Of course, those are from Nikon Ambassadors, but it's encouraging.

Not for me.  I've had brand-name cards go partly bad (continuous high limited to 1Hz) and completely bad (unrecoverable iimages).  In both cases the dual card saved the day. Not everyone needs / ...
