D750 noisier than D800?

Yes, the D750 is way better at higher ISO.

Probably the most exaggerated thing that comes up in this forum. All the charts I've seen show the D750 and D800/D810 to be very close at all ISOs. The 36 MP has more resolution, so at lower ISOs you can print larger, that's the main difference between these two cameras. A lot of D750 owners are going to be upset if Nikon updates the D750 and puts the D810 sensor in it, which I suspect is what they will do.

I can't see that ever happening. Putting the D810 in the D750 would be a step backward in high ISO performance with its smaller pixels.

This is another often cited and wrong argument, that pixel size determines high ISO performance.

And I imagine the D750 market is not looking for 38 Megapixels either. I can see the D750 successor getting an FX version of the D500 sensor or equivalent. It will have amazing high ISO range and performance.

Like I said, if Nikon reuses what is a very good 36 MP sensor in a D750 update there will be a lot of moans from some people.

Believe it or not, there are no exposure issues when I find this difference between the D800 and D750 base ISO recovering shadows. Their behaviour is different in this case, no sense to search for human mistakes. I just wanted to know if anyone has experienced the same. We all read charts but real shooting is quite different ;)

Shooting at base ISO 100 and exposing for highlights, it's well known that the D800 has a dynamic range that lets to get detail from shadows when developing the RAW file, with almost no noise.
Trying to do the same thing with the D750, I've found that it seems to have more noise than the D800.

As far as I can tell, the sensor’s native response and dynamic range are not heavily biased to shadows (like the D800) or highlights (like the D810) but is somewhere balanced in the middle, with good recoverability on either end." http://blog.mingthein.com/2014/10/17/soi-bought-a-nikon-d750/

So based on this if you are exposing for grey card you would see:
  • D800 to have more shadow recovery but least highlight recovery.
  • D810 to have most highlight recovery, but least shadow recovery.
  • D750 to be in the middle. Less shadow recovery than D800, but more highlight recovery. Less highlight recovery than D810, but more shadow recovery.
In pure RAW data without default curve applied you would see shadow noise floor is about same number of EV steps from highlight saturation as all three cameras have very similar RAW DR at base ISO.

Exposing for highlights is camera dependent and you can still get different amount of information in highlights.

This makes sense to me, thanks.

The D810 has slightly better shadow noise performance than the D800. Yet the D750 vs D810 +6EV shadow push I linked to shows the D750 being on par with the D810, thus your D750 is better than the D800 rather than being worse.

Okay - that's what counts - for you :-)

Then look at Bill Claff's post lower down in your thread. Graph of D750 and D800.

We all read charts

Charts can be useful because they can inform as to what is possible.

It's more than real life shooting, it's also real life processing:

I'm not seeing "way better" here.

I would like to see side-by-side NEFs of the same scene with the same exposure. My thinking is that this will be mostly a matter of Raw conversion and post-processing.

I'll do it, mainly because it's important for my work. But my impressions are that: 1)The D750 is clearly better at high ISO (from 3200) than the D800; and 2) The D800 recovers shadows better, subexposing harder, than the D750 at base ISO 100.

I'm not saying this is technically true, these are MY impressions working with both. My impression is not a review, and a review will never do my real work. Still remember when reading "excellent reviews" for the Nikkor 24-70 f2,8. None of them told anything about its corner issues at close distances...

Charts and reviews are useful indeed, but the main thing is how you shoot, and process of course.

These are lab measurements D750 vs D800:

Lab results are for reference. Since every shooter is unique in his experience, it is therefore not unreasonable to expect that different shooters will have different results.

Not really. I've tested mine side by side and there is so little in it as not to be worth worrying about.
