D850 ISO 12,800

Discussion in 'Nikon FX DSLR' started by Marlene, Sep 10, 2017.

  1. 100% crop of my dog's fur at ISO 12,800. The first photo is OOC and the second with a bit of noise reduction and nothing more.

    ISO 12,800 OOC.

    ISO 12,800 Minimal Noise Red..

    Marlene, nice! have you tried at some more "normal" iso..say 3200ish?

    Can you post a link to a full size jpg, please
  4. Here are jpegs shot at ISO 100, 500, 1000 and 3200. Sorry not great subject but all I had time for today. Can do more tomorrow.

  6. Not impressed with the iso performance @3200. Sorry.

    That's not good since that's my target ISO for the D850
  8. Kinda disappointing so far.
  9. Not good. I guess there will be more people making test shots. Lets post them people!
  10. I added a couple ISO 4000 DNGs to the file. Will try to get more 3200 tomorrow for ya.
  11. About what I expected. The small pixel size of the sensor is not going to give the same high ISO performance of the larger pixel FF bodies. If you re-sample to a D5 size image you will likely see D5-like high ISO noise levels. So to me that is one of the great features of the D810 and D850. In good light and near base ISO they produce exceptionally detailed images that can be printed very large. At high ISOs they can duplicate D4/D5 ISO performance if the files are re-sampled to match that of those bodies.

  12. really?.. doubtful. The signal to noise is much greater with the D5 due to the photosite size.

    what i expect is that you don't want to shoot greater than ISO=1800-2000 as is with D810 or D800 for that matter.

    and as is also true for the D5 it depends on the light. i have examples of D5 ISO=12,800 shots that are stellar and ones i had to delete they were so bad.

    The voice of reality, thanks
    If the max is 1600 that could be a show stopper, hell that is a show stopper. I'll just stay with what I have
  14. Here is what I read on DPReview (Nikon D850 First Impressions Review),

    "Sure enough, just like the D810, if you brighten the D850's ISO 64 shots, they exhibit more noise than if you shoot at the same exposure using a higher ISO. Add a little more amplification at the bottom end, by starting at ISO 100 and the results are very similar to those you get by natively shooting at ISO 6400 (both of which are noisier than the ISO 64 series of shots, since they were given less exposure).

    Once you get above ISO 400, where the sensor mode changes, there's no essentially no difference between shooting at ISO 500 and brightening, vs shooting at ISO 4000.

    By ISO 4000 and 6400, you can start to see the D850's higher gain mode showing a slight noise improvement over the D810: a difference we'd expect to see as the ISO settings rise further. We'll be able to look at this when we publish our studio scene images in the next few days."

    DP has a way of saying nothing by using too many words. I continue to have a feeling we got duped and Nikon took parts (AF, FPS, etc) from other bodies, bumped the MPs and put it in a box, time will tell

    I am a fan of Brad Hill. His initial test indicates disappointment in the noise department

    How did the D850 actually stack up against the other cameras? Consider a D850 raw image file captured at ISO 3200. At what ISO in the "other" cameras do you see comparable noise?

    A. With D500? ISO 3200 to ISO 4000 (so just very slightly better than the D850 - in the 1/3 stop range at most).
    B. With D800e? D800e: ISO 4000 and in some shots ISO 5000 (so noticeably better than the D850). Note that the D800e and D810 are virtually identical in this regard.
    C. With D5? ISO 8000 to 10,000 (in a class of its own...which isn't at all surprising when you compare the pixel pitch of the cameras being tested).

    Another observation was very obvious when I was going cross-eyed looking at all these images - the D850 seems particularly high in luminosity noise.

    Another way of looking at ISO performance is examining the ISO where one first can see colour noise or luminosity noise (when viewing raw files at 100% magnification on a 110 ppi monitor). So...

    A. When does colour noise first become visible on the various cameras (i.e., at what ISO do you need to begin suppressing colour noise during raw processing if you care about producing noise-free full-resolution images when viewed at 100% magnification)?

    With D850: At ISO 400
    With D500: At ISO 640
    With D800e: At ISO 400
    With D5: At ISO 1000

    B. When does luminosity nose first become visible and require suppression?

    With D850: At ISO 400
    With D500: At ISO 640
    With D800e: At ISO 640-800
    With D5: At ISO 1600

    I've never seen so many different reports about anything
    I can't believe Nikon blew it so bad that they made an FX camera that's not better than a DX camera. The backlash could be ugly if it's true. I get mine Thursday and I'll know before Friday is over. If it's true the D850 can still be a good camera, just not the all in 1 they bragged about.

    The more I think about the D500 high ISO being better than the D850 it's just not credible that all the pre release testers could miss something so important

  19. The re-sampling to D4/D5 resolution creates the effect of a larger photosite. Much of the noise gets eliminated in the process, while detail is preserved.

    This is not something I read on the internet. I shoot with both the D4 and D810 and find the high ISO results pretty much identical if I keep the resolution the same through re-sampling.
