Need a little help from the community. Thanks in advance.
I recently purchased a D810. Overall, I love it. Recently, I took an autumn afternoon shot of a tree top against a deep blue sky, at iso 400.
In the sky, there seems to be significant noise (viewed in camera at 100% zoom). I'm not tech-savvy enough to know what type of noise, but I would think that at 400 iso, a clear blue daylight sky should be virtually noise free, even at 36 mp. After raw processing (Aperture) it is the same. High iso noise is not the issue - this is low iso where I am surprised it is even there.
I've since taken other types of "test" shots and I'm recognizing the same type of 'noise' - or at least I think so.
I've looked at any article I can find about D810 noise and - to my eyes - no one seems to have an issue at iso's lower than 1000. I can't seem to 'see' the same thing in other folks shots.
So I don't know if this is normal (as in I'm looking too critically at it, or I'm imagining it?), or very odd. Perhaps I have a lemon? Maybe it's just a blue sky thing?
I'm hoping you all can take a look at the original raw image straight from the camera and give me your quick thoughts. View it at 100%.
Basically, I'm looking for either "no, that's normal" or "holy shit send it back".

I was shooting the previous evening at 400, and forgot to put it to 64 at the end of day (which I usually do.)
It was with an older 50mm D lens, but again, I've shot with that lens on other bodies and never noticed anything unusual.
Regarding noise in a 5 year old camera, I shot for years with my 6 year old D300 and never, not once, thought "hmm, that's a fair bit of noise at 400." Maybe 800 I'd start to notice it. And never on a blue sky. That's why I'm wondering if it's a function of the tiny pixels, or something else possibly faulty.
So far, there doesn't seem to be a consensus. So I'm not sure what to think. The camera store where I bought is a good hour away, so I can't just pop in, and anyway, it is in their interest to say there is nothing wrong with it.
I could use in-camera NR, or Nik's Dfine in post, but that's brings me to my original point - I'm surprised I would have to do that with low iso's.
I'm grateful for all the comments, so please keep them coming.
Because it has such a high MP rate on a FF sensor, what is going on is that when you view the images at 100% on your monitor, you're actually zooming into the image far more than what you would be if you were at 100% on a 12Mp camera. So you're seeing noise in the 36Mp file that you wouldn't see in the 12, or 24Mp file. Does that make sense?
When you normalize the image, you actually get a very similar noise pattern that what you'd see on say a D600/D610, etc.
One thing you might do would be to downsample the 36Mp file to something 1/3rd or 1/2 the size and then view it then.
Or, as some of us are approaching as old as dirt, we remember the days of film, and grain. So, even with the noise at ISO 6400 in a D800, which I think is getting objectionable compared to the D4, I have no issue with a basic characteristic of digital photography.
Somehow Phase One keeps running through my head….
Another idea might be to look at some of the masters of the film era. Some of the most valued photos in existence have lots of technical issues, but the content is what is considered to be of value.
Good luck
If you look for noise by pixle-peeping, especially as JonMcGuffin and others has written, on a very high MP system, you will find noise. That does not make it a bad picture nor a bad camera.
Display the picture as you expect the viewer to see it (onscreen or print) and see if you can see any noise. If you can see noise, then you may have a problem. If you don't see noise, you ain't got no problem.

And, yes, it will restore all the factory default settings

Next step is contacting Nikon, I suppose.

People here say that the usual ETTR method doesn't work with the D800/810 in fact you should ETTL and recover lots more detail from the shadows - I don't know because I haven't got one but I do know there is no magic that stops noise being exaggerated by ETTL when pushing in post.
Your shot may have been pushed a fraction in post with subsequent boosting of noise as above? I don't know because I wasn't there, but the noise looks OK to me considering how large that image would be if you could see it all on the wall instead of pixel peeping a fraction of it on your PC.
Just my 2c!
I'm still not convinced you have an actual problem, did you compare to a different D810?
In the down sampled square above, from my image, Pitch-black wrote it was "barely visible", but that seems heavily noisy or pixelated, keeping in mind it's a low iso 400. My 6 year old D300 never showed a blue sky like that, even towards iso 1000 and above.
I know this is an older post but I am going through the same thing right now. Did you ever resolve the issue?
Still, I'm glad I did it for peace of mind and don't consider it important anymore. If I have a shot with noticeable noise, at any iso, I use the excellent Nik Dfine.
