I was excited to handle the Nikon D850 for a couple of hours...
(http://www.myphotogallery.name/D850/D850rev-1.jpg)
While the camera I used was a pre-production model I do not have the right to publish images taken during the try out time.
For pictures with D850, I will complete my user review (http://www.nikonuser.info/fotoforum/viewtopic.php?f=33&t=3353&sid=2b6d8dedd7fc48b17c516f67ea0583c5) when I get my own D850 in a couple of weeks.
Not being allowed to post any pictures taken doesn't mean I can't write something that probably might interest you though...
first impressions:
• If you are common with or if you have a D800 or D810 ànd a D500, you will recognise inheritage from both. Body size being a little smaller than D810, button layout similar to D810, tilting LCD and iso button placement like D500. The D850 also has a dedicated AF point positioning joystick, just like D5 and D500.
• The D850 viewfinder is... simply out of this world and one of the things I like the most about this camera. It's a dream to look through even if your distance is a little further away because of your glasses in between.
• Even though I will never shoot this camera in DX mode(it does nót change fps speed), I tried a DX lens and the clearly marked DX surface is now more than big enough to use confortable.
• The AF is a direct heritage from D5, with some improvements while using Live view.
• IQ is simply stunning straight out of the camera :o , I love the new "auto" picture control setting.
• DR has even increased over the already extraordinary DR of the D810, especially while going into higher isos.
• IQ at high isos is to my opinion a full stop better than what I got with my D810 when printed or viewed in the same size.
• While looking at normal screen viewing and A3+ print, 25600 now became as as what my D750 delivered (http://www.nikonuser.info/fotoforum/viewtopic.php?f=33&t=2828&p=7419&hilit=iso+25600&sid=0e58a797e23428c4dbb89271f0f5f810#p7419), but with more detail and mcuh more resolution...
• Camera operation noise is clearly more nervous than D810, noise level somewhere between D800 and D810, over a relative silent Quiet mode(more silent than D810), to total silence while used in LV.
• You can use the D500 or D810 battery in the D850.
• The touch screen has significantly improved over D500 while U can use it while scrolling the menus. Great!
• 9 fps with grip makes it a perfect sports camera.
• I use a 128GB XQD, and that's what you need if you shoot uncompressed RAW
• The illuminated controls makes the D850 a joy to use at night...
I was testing the D850 with 20mm F1.8, 50mm F1.4, 105 AF-S F2.8 macro(+500 pictures...), 70-200 F2.8 AF-S VR FL, the mighty 200-500 consumer lens with pro grade IQ, and finally with my prehistoric, distortion free 28-105 walk around lens...
Is the D850 an interesting replacement for a D800 user: Definitely!
Is the D850 an interesting replacement for a D810 user: Worth considering but D810 is still a fantastic camera, even with his successor arrived...
Thanks for your attention and kindest regards,

Thanks for the review Stany.
The D850 sounds more and more like it will be my next camera. The viewfinder improvement is a big plus to me.

Dear Erik,
Thanks for your kindness. Nikongear is a very nice place.
On dpreview I just got banned for the same topic by Thierry-TOF guy (http://www.nikonuser.info/fotoforum/viewtopic.php?f=33&t=3355&sid=730f14efefa104dd6db27ef429e5bf04) after over 15 years of relative valuable contributing because of my website in my signature. ;D
All the best and kindest regards,

There is some talk on noise in base and low ISO.
Have you any comment on such?

Depends on whether you look at very high magnification/pixel peeping vs. normal view or A3+ print.
When I compare in A3+ print size or normal screen viewing, even iso 25600 seems relative clean, comparable with D750...
It's a pity I cannot post portraits I made from my wife with the D850 from iso 64 till iso 100.000, because she looks fantastic even at iso 102.000 :)

Why not?
Would be interesting to see the result.

The big question for my work: Is the base ISO of 64 as good in the D850 as in the D810? Do you have any thoughts on that, please?

My personal opinion on your question after several hundreds of pictures. Not as good... better. :)

If so, that is good news for me. This may be the perfect camera for what I do, at least the next step until Nikon produces an award-winning mirrorless.

Did it have a lock on one of those memory banks or do we still have stupid pro controlls ?

I handle one today to try a couple of things I was interested in. In sounds wonderfully, it is fast, and it does shoot in complete silence with focus peaking -it works very well with the 85mm 1.4g at 1.4- as well as focus traking even at f1.4. Ergonomics as expected -very good too-. All this from 5 min play with it. No files to review at home. Iso 6400 looks very good as well on the camera´s screen. Will wait for more detailed and deep reviews.
-

If I understand the difficulty with the memory bank getting inadvertently changed while in the field there is a work around. Save a BIN file to a memory card and the save it to your computer. After formatting a memory card copy the BIN file back and write protect it. Now you won't accidentally over write your defaults.
If you do not write protect the BIN file on the secondary memory card you can save a new BIN file there.
I only format memory cards at home and only after uploading and backing up incoming file to three HD(s) on two computers.
Any time I load my settings I'm assured that my, not Nikon's defaults are in place. Also I'm protected for my own errors.

.... it does shoot in complete silence with focus peaking
Can you describe a little more how the "focus peaking" has been implemented?
I always assumed it was something that the mirrorless camers used through the EVF.
- Is the D850's version done via the external LCD?
(I've heard some people just mentioning a slightly better green dot)
- What was it like to use in practical terms
(given that many here like the optical VF and mostly work with the camera held up to their eye, not out in front)
-
It works like in the Fujis, using the lcd to highlight whatever fringe in the image is in focus, instantly and acurate with the 85mm1.4g @f1.4. Even from a couple meters away it distinguished between ears,face, eyes, etc
It works on video too but only in hd so far -no 4k focus peaking- and you have to decided the help you need: zebra pattern or focus, not both simultaneously.

I'm very hyped about the D850, hopefully I'll be able to get a copy by mid-October ;)
The DR is slightly better than the D810 and slightly worse than the a7r2, but base 64 ISO! Oh, and ISO 12800 delivers clean images as well. This is simply stunning. I was going to get a D500, but why should I? I'll have the D850 paired with a used D7200 rather than D810+D500. It's a bit more expensive, but I only paid $1000ish AUD for my D810 so why not. :D
Nikon is on the right track in my opinion. Recently Canon released 3 new tilt-shift lenses, 50mm, 90mm and 135mm. Nikon's 24, 45, and 85 needs an update to allow tilt and shift on the same axis.
If Nikon doesn't goof this one with another D750 ploy, and if Nikon can give us an adequately spec'd mirrorless FX, Nikon shooters are on a roll! I personally don't care much about mirrored or mirrorless, but economically, it makes sense for Nikon to ride the wave as the market is maturing soon.
-
I was offered a very nice 72-month 0% deal :o :o :o
-
Handled D850 briefly at Yodobashi today.
Even though it doesn't employ the monocoque construction, the body feels a bit thinner than D810, and the grip feels a bit more pronounced. The holding feels thus a bit more stable.
The shutter sounds a wee-bit brighter than that of D810, but virtually almost identical. The sample was attached with 24-70VR zoom and the combo focused swiftly.
-
I'm wondering if anyone has had a chance to try out how the split-screen display live view zoom works on the D850. On the D810 and D5, you activate it from LV by pressing i and then selecting the split display. This opens up two views along the long axis of the frame, which you can zoom and move about but they are on the same rows of the image. I am interested in finding out if there is a possiblity to move the two windows independently so as to check focus diagonally or along the short axis in the image. This is mainly of interest to use of tilt shift lenses and specifically adjusting tilt and focus.
-
While I would like a mirrorless FX Nikon, I don't have to have it. For one, I seldom to never use the optiical viewfinder on my D810, but instead use the LiveView all of the time. So, any improvement in the LIveView screen (which the new D850 has in spades) makes my life easier. In fact, LiveView is the same as an EVF for my use.
-
I was very interested to learn that Nikon abandoned Monocoque construction for the D850 because I have long-suspected that the failing shutter and uneven focussing problems which have plagued some of their recent models was because those components were not mounted onto a strong and rigid metal chassis.
Chassis-construction is something that I personally consider to be an extremely important part of the build and is one of the reasons that I stay with the D# range and preferred to shoot with a D3S until I was able to obtain a D5.
(The lack of twin matching card slots was my principal reason for sitting out the D4 series and is something that I don't like in the Specs for the D850.)
-
The D800 had full metal chassis and plenty of AF problems. The D810 (which has the new material mirror box) is much more accurate and consistent, though this may or may not be related to the construction used.
Optimal fine tune settings over my lenses had the following means and standard deviations over my set of AF lenses:
D3X 5 +- 5
D800 -9 +- 9 initially
D800 1 +- 8 after service
D750 6 +- 4
D810 1 +- 5
D5 2 +- 8
The D810 is the one of these which required the least fine tuning with my lenses. Though the D5 is the easiest to fine tune (because with most of my lenses the automatic fine tuning worked perfectly).
Now, this doesn't tell us how stable the AF is over long term or how it survives impacts. It only shows how much calibration was needed and how much it depended on the lens.
The D800 was dropped once and indeed the AF went off, which is how it ended up being serviced. The mean was after service much closer to zero but the lens to lens variability did not go anywhere.
-
The D800 did not have a full-body metal chassis in the way that the Dx cameras do but only had a pair of light-weight metal frames and the rear one could break quite easily under the slightest impact.
The metal lens plate in the D800 was mounted only on composite; and the mirror-box was another weak construction.
I use my cameras in wild places and although I do try to be very careful with them, i wouldn't trust a body which did not have the strength and rigidity of the Dx range.
-
D800 looks metal to me, where is the composite?
http://www.bythom.com/_Media/d800_bodyframe_med_hr.jpeg
I am sure the D3/D4/D5 is more rugged but most people are not willing to carry such things around. There is also the matter of payment ... ;-)
I believe the use of composite mirror box was brought out as a way to reduce weight and avoid the problem of misalignment. Whether it achieves that end is of course something that I don't know. I do know that the AF in my D810 has not needed further adjustment after initial fine tuning was made, during the three years I've used it, whereas with the D800 I was in constant struggle with the AF.
The D5 autofocuses excellently of course, and I haven't had any problems with it.

Ann,
I think you are confusing the D800 construction with the D810 construction however I've heard about the D800 rear end cracking so I'm sure it's lighter construction than the D3 series, D4 series and the D5. The front bayonet is mounted against alloy.
I'd have bought a D4s instead of the D800 if I could afford to and then I'd be foaming at the mouth when the D5 was announced. Have I heard of the D800 cracking around the tripod socket? I think I have but I'm not sure.

Has anyone seen a similar front view of a D850? I've seen a rear view and I think there is a reason. I'll bet the D850 does not have an alloy mirror box but one like the D810. An implied lie? Let the suckers believe what they want? I'd still buy the D850 if I could.
I wonder if the D850 mirror box to bayonet has been strengthened in some way? Mercedes-Benz patented crumple zones in car design then did not enforce the patent as crumple zones save lives. Does the D850 have better crumple zones?

-
The lens receptor plate itself on the D800 is metal but it is screwed into composite with self-tapping screws.
The total weight of a camera body is not something which concerns me personally; but the degree of ruggedness and its ability to withstand heavy use under all kinds of conditions matters to me very much indeed.
-
When Nikon released D750, an engineer in an interview to the D750 development team admitted that the monocoque construction allows the mount and the sensor to be fixed directly to the mirror box so that the full optical system becomes one unit. This unit is sort of floating in the monocoque frame, and the shock taken at the mount of the body (for example, caused by the lens hitting something hard) can be absorbed to some extent by the kind of "loose" relationship between the frame and the mirrorbox unit.

yup, the bottom of the d800 chasis is brittle, mine broke and it wobble when mounted on a tripod, took it apart some, epoxy it, and has been fine for 3 years or so

Hi, as others have pointed out, the D800 had a metal body. This was changed in D810 where the front part is not metal.
Nikon has not released the body skeleton pictures of D810 for this reason I suspect. It appears that the D850 will have the same construction as the D810.

What I am wondering, it's about the focus stacking feature' technology :
# by sensor back and forth motion, like some Olympus bodies;
# or an electronic device acting on the focus ring which involves the use of an AFS lens ?

Since they limit it to 2 particular lenses, the 60mm Micro-Nikkors, both of which have AF, it is the second choice, the use of AF in the lens, not moving the sensor.

I don't think this is correct. Without doubt it uses the focus motor but is not limited to particular lenses.
Imaging resource's interview with the designers included this: "Because focus and depth of field depends on the lens you're using and the distance to the subject, it's often confusing how large a step you should specify between shots, when using a feature like the D850's focus shift option to capture images for use in focus stacking. In the case of the D850, you can choose a number from 1 to 10, and we asked the Nikon engineers what those units corresponded to. The answer was that the finest gradation (a setting of 1) equates to a focus step equal to the lens focal length divided by 30. So with a 100mm lens, the smallest step would be a distance of 3.3mm, and the largest one 30mm. "
There would be no point in suggesting a formula to use focal length to calculate step size if only one focal length (60mm) could be used.

I think you are right. I made a mistake. It is the slide copier that is sized to the 60mm. Sorry.

I see. No problem.
In the brochure Nikon say "first, set an optional ES-2 Film Digitizing Adapter onto a lens such as the AF-S Micro
NIKKOR 60mm f/2.8G ED attached to the D850". I think it should be able to work with other lenses but one might have to hack something together to accommodate the different working distances of different lenses.
I think the key is how to get the film at the right distance from the lens and how to shield the front element from stray light if you go for a longer working distance.
The 60mm AF-S is very good at 1:1 in my experience but I have a duplicating lens (the 75mm Apo Rodagon 1x) which I suspect may be a little better since it's optimized for this magnification. I am planning on getting this ES-2 to speed up the digitization of my film shots and see whether the 75mm could be used as well.

12800 looks very usable. Even 25600 looks like 400 speed color film. We have come a long way towards seeing in the dark.

I am planning on getting this ES-2 to speed up the digitization of my film shots and see whether the 75mm could be used as well.
The ES-2 just holds the film at the right distance to get 1:1 - closest focus in the case of the three Nikon's it is designed for. On an FX camera that means using a 60mm micro and on a DX camera the DX 40mm micro. Closest focus for the 60/2.8 G is 18.49cm, for 60/2.8 D it is 22cm and for the 40.2.8 DX it is 16.3cm, so the ES-2 includes adapter rings for the 60/2.8 G and the 60/2.8 D. The 40/2.8 DX does not need an adapter ring because it has the closest close focus.
So if the Apo Rodagon achieves 1:1 at closer than 16.3cm, you won't be able to use it with the ES-2. If it is 1:1 at longer distances, you can, but you may need a special adapter ring to get the distance right, or tolerate some cropping or wasted pixels, as the case may be.
-
The ES-2 is mounted on the lens using an adapter, right? So the critical parameter is the working distance (i.e. distance between front of the lens and subject) and not the distance between the sensor and the subject, right?
-
25600 seems very good, given your shots were taken with a pre production sample, there seems to be a chance to make 40.000 usable in post...
-
I have been revelling in being able to use ultra-high ISO and to be able to shoot just about anywhere, at any time, and under any conditions. I find it liberating and exciting to be able to photograph where I never could previously.
Colour rendering seem to hold-up remarkably well even at those settings and my approach is to ameliorate the Colour Noise but leave Luminance Noise alone.
To me the slight grittiness of Luminance Noise is of no concern but I really dislike the mushiness which results from using Luminance Noise Reduction.
-

Correct. The only helpful information I have seen is on the Nikon USA site in the form of Nikon's answers in the Product Forum for the ES-2 (http://www.nikonusa.com/en/nikon-products/product/miscellaneous/es-2-film-digitizing-adapter-set.html#tab-ProductDetail-ProductTabs-Forum). That does not include physical specifications, but assuming it is true that the ES-2 mounts on the 40 DX without an adapter it itself must be about 16cm long, closest focus for the 40 DX. The Apo Rodagon 75mm is said to have a working distance of 11.8 cm at 1:1 (http://coinimaging.com/aporod75-4var.html) so you won't get 1:1 with the ES-2 unless you take a slice out of it and re-join the ends.
Another issue would be the filter threads, which are 62mm on all three of Nikon's designated lenses, so presumably the ES-2 is also 62mm. Adding step-up rings would add length.
If you don't get 1:1, all that means is wasted pixels, which in the case of the D850 is not likely to be a major problem. You might lose some of the speed advantage getting accurate focus. Of course, the accuracy of focus with the ES-2 depends on how well made Nikon's holders are and how well they fit the slot in the ES-2, which we don't yet know.
Nikon's price for a plastic tube with a threaded end is outrageous, so I am going to wait for the $5 copies to appear. With a bit of luck an enterprising person might even make one to digitise medium format negatives.

According to Nikon the D850 has the SAME dynamic range AS the D810.

Making thin threads into a plastic tube is quite difficult.
Medium format digitized with one frame of a 35mm format camera would be seen a bit of a downgrade IMO. I didn't shoot 6x7 cm film in order to copy it with a 35mm camera.
One way to digitize medium format is by stitching, but then you need a way to get the pieces to match perfectly. Low distortion in the lens should help.
Problem with film is that for optimal quality you need to use a microscope lens and those cover only small pieces of the film at a time ... so it gets quickly complicated and one may have to decide on a "good enough" technique never getting the true details on the film in the digital realm.
If the plan is to display film based images on the computer, put them on a web site or print small, the finest details should not be a problem and I would hope the D850 can do the trick. Scanners had techniques to reduce the impact of grain and dust (GEM and ICE) and I felt both worked very well on color negative film. I would guess this problem would show up when using the D850 in place of a scanner: not all the software options are available. Of course there is noise reduction software available but are the algorithms in current noise reduction optimized for the noise structure of film? I would think they are not. Years ago I felt NeatImage to give an excessively polished look to scanned images and actually preferred GEM in the Nikon Scan software (which is no longer supported) for color negatives for a natural look.
-
I have not tried to camera-copy color film; I prefer to use a scanner with specialised software for that purpose.
The Nikon Bellows units have film holders and second-hand ones can often been found on the Internet.
NikonScan (Mac) will only run on old (pre-Intel) Macs but SilverFast has excellent software and a current driver for the Nikon scanners although I believe that NikonScan 4 still runs on Windows computers.

I tried the ES-1 with color slides on my D600 and was very satisfied with the results. I sure cannot see more details on a large wall projection. I expect the D850 to outperform my color shots. I did use 400 ASA film most of the time and I am quite positive that I did not use the best hand holding technique and because I did often shoot in low light, manual focus most of the time and Aperture between f/1.4 and f/2 I am quite sure that critical focus for super high frequency information was not recorded. If the D600 can resolve the grain in all its beauty, the D850 will "only" add bezter color fidelity.
Yes the Nikon Scanners are very nice and time is not so much of an issue if you run batches of 50 slides in auto mode.... BUT: for the casual scan to sell for even large prints the DSLR quality is more than good enough!
I can upload a full size D600 scan and even a D850 scan of the best shot I can find spontaneously if it helps. I also have the PB4 bellows here with slide copier attachment.
