jhinkey: Any idea of the actual flash duration - 1/8000 sec shutter speed sync doesn't actually say how fast the actual duration is. Could not find it in their technical info section.

A Nikon Speed Light at lowest power has a very short duration flash of 20 microseconds or so if I recall, which was too long for one of my recent photo applications (so I built my own, 5 micro sec flash, which was a pain).
If this flash can to 10 microseconds or less with a pretty reasonable shape to the light curve I'd be very happy.

K E Hoffman: As someone who was there just miles from where this was taken. This video does not even capture the experience. Heck the exposure was not even corrected well enough to capture what as a spectacular corona this time. I like seeing the prominences but I can see those in still shots.
This for me is a case of too much gear not enough art. It isolated a spectacular and very emotional event for many into data collection.

Harsh. The video captures what the vast majority of people did not see with their eyes. Using my 600mm + 1.4TC + solar filter I had a live view feed on a screen that people could see and they loved it since they couldn't see much detail with their eyes using a solar filter.
What I find really nice about this video is that it captures just before and just after totality so you can see what that looks like in real time - not something you can see with your eyes (even looking through a lens) or with still images.

falconeyes: Overall, I very much like this video and the circular motion around the sun's circimference. But the effective resolution is FullHD at best, no need to make this 4k. A better use of 4k would have been a wider angle, also better capturing the moment, I guess.

Moreover, I heard the corona was much wider than captured in this video. An s-log video color-graded to show it all would have been appreciated (by me).

s-log would not have shown it all. To get a large extent of the corona with 14 bits of DR still requires the prominences to be way over-exposed.

steelhead3: I am surprised that smoke from all the fires didn't get in the way...fires burned right up to Ka-nee-ta on the Warm Springs Reservation (completely rented out to a Japanese group)

The wind was favorable that day in Oregon. I was East of Warm Springs near the Idaho border and there was a faint faint haze still present, but it didn't cause any real imaging problems. We lucked out that smoke and clouds cleared out for the big event.

Very very nice. Having photographed the eclipse myself (both with and without filters) I know how not easy this is to do.

Link | Posted on Sep 5, 2017 at 16:57 UTC as 18th comment

This being my first eclipse I was afraid of frying my D800 or A7RII, but being an engineer I did the math, did the research and got the right filters (made my own from stock filter parts actually to custom fit my tele lenses). Still, when the eclipse ended I had to be fast to cover up the naked 400mm + A7RII that took awesome images during totality. The 600mm had aperture mask + IRND filters the whole time.

Looking forward to the next eclipse using even better gear.

What's missing from the article are images that illustrate what's being said in words and charts, as that's what most of us see from our photographic devices.

Sure in some cases going from 12 to 14 bit, even at high ISO, just resolves the noise in the shadows, but typically the shadows are lifted a lot and the highlights are pulled back down. The result is more natural shadow noise (less clumpiness/banding) and less banding in general.

If you don't need to make drastic post-processing changes to the shadows and highlights then 12 bit tends to be just fine.

Good that they were charged and even better if they face some stiff penalties.

Now for the comments from those that think that what they did was acceptable in some way . . .

It would be so much more useful if it had interchangeable lenses.

Interested in the resolution at 1,000 FPS - the RX10 went to really low resolutions at this max. FPS and was not very useful.

Please don't make me watch the entire video to see if there is any tiny tidbit useful information that hasn't already been discussed already. My attention span is too short . . . what was the video about again? - I've forgotten just typing this comment.

jhinkey: The D850 is just the next evolutionary (not revolutionary) camera in the excellent D8XX line and really it's what we all would and should have expected from Nikon - continued gradual improvement in the product line via better specifications (like bump in MP, better AF, etc.) and addition of some new-to-the-D8XX line features (like tilt screen, illuminated buttons, etc.).

There really isn't anything revolutionary in the D850 - Nikon never lost it's mojo in the DSLR realm, so its silly to say it has its mojo back. It's just not sure it has its mojo in the overall digital camera world depending on where the whole industry is going.

Will I upgrade to the D850 from my D800? - maybe. Maybe I will entirely switch over to Sony because mirrorless fits what I need better in general. Maybe the D850 will be a temporary thing while I impatiently wait for a Nikon full frame interchangeable lens digital camera.

Good stuff the D850, but I don't see the justification for all the excitement,

@gskolenda -

I already own the A7RII and love it for hand-held light weight compact excursions. The Sony can't hold a candle to the D800 (or D850 for that matter) for tripod work or squeezing the every last bit of DR out of a scene, but the D8XX is a tank to carry around. So I own both and am happy to do so. My D800 is getting pretty worn down and its few deficiencies are really starting to wear on me now that the D810 is very reasonably priced and the D850 is going to be available.
What I really want is for Nikon to be truly revolutionary and make two full frame mirrorless cameras: one to compete with the Sony A9 and one to compete with the A7 series (and keep making D8XX cameras too for a while).

The hype for this excellent camera is just a bit overblown IMHO.

Hey - I'm in that picture (somewhere down there in Eastern Oregon)!

Lee Saxon: Does the news that EFCS with Mirror Lock Up requires two shutter presses mean that the D850 for some reason loses the "Exposure Delay" mode I use almost daily on my D750? That would be a bummer.

Barney - what's the sensor readout time in fully electronic shutter mode?

Paul Petersen: How about a DX solution.....
My Dad has a ton of slides and no time to futz with a scanner.

You should be able to get this to work with a DX DSLR as well.

Yes.

At that price, the ES-2 should come with the D850 for no extra charge!
