Dear readers,
I have to say SORRY because I screwed up the previous post about the ISO performance of the D750. When editing the sample images I did not turn off the noise reduction in Capture NX-D, thus the high ISO images were mashed into a blurry pulp without any noise. In my defence I have to say that this was the first time I used Capture NX-D (since Lightroom can’t read the D750’s RAW files yet). On the other hand I could have noticed by looking and thinking for just a second. I withdrew the post from the blog and here is the new version – this time with noise in the sample images.
All images taken with the NIkkor 50 mm at f/8 at aperture priority. ISO was changed manually to 100, 200, 400, 800, 1250, 1600, 2000, 3200, 6400, 12800, 25600 and 51200 (last one D750 only, the D800 stops at 25600). Click on the image for a larger view. When looking through the samples I have to say it is hard to determine who performs better. Both cameras start to show noticable grain at ISO 6400, but images stay quite usable up to ISO 12800. “Usable” depends on your personal standard and the intended use of the image. I personally share many images online at a resolution of 2000 Px (long image side). A lot of noise “drowns” when the image is downscaled from the full 24 (D800: 36) megapixels.
This comparison is a quick shot at the D750’s performance. There are other websites who can do such tests under lab conditions and are far more technical at evaluating the results. My intention is to show you some images and give you a reference on how the camera performs in high ISO conditions.
Attention, large file !
****Update October 3rd, 2014****
I used Capture NX-D (the free version) to process the files. In the original post I wrote that I used Capture NX, which I do not have. Thanks Roland Mathis for the comment !

Thanks for this comparsion. D800 is still looking very good.That helped me alot with my decision! High Iso performance is very important for me 🙂 Daniel
u should have shoot in a dark environment since we only use high ISO in dark environment for this comparison.
Agreed
Hello and thanks for the test.
I have a question : you say you used capture NX to read the D750 images ??
This makes me wondering, I thought the last camera wich Capture NX (now discontinued by Nikon) can read was the D800 ?
I think you speak of Capture NX-D (the free version without U-points ?)
Hi Roland,
it’s Capture NX-D, you are right. Post updated.
