Nikon Df(D4) vs D800 Low ISO Performance:
Also, the below are 100% crops, without any down-sampling applied. If the Nikon D800 images are down-sampled to 16 MP resolution, the files will look much cleaner.
1. ISO100: As expected, both cameras handle base ISO extremely well.
2. ISO200: The same is with ISO 200.
3. ISO400: At ISO 400 the Nikon D800 has a tad more noise in some parts of the image. However, keep in mind that you are looking at pixel-level performance. As I have mentioned above, down-sampling to equal size will diminish these differences.
4. ISO800: At ISO 800, the Nikon D800 shows more noise, especially in the shadows.
5. ISO1600: At ISO 1600, the differences in pixel level noise are pretty clear – the Nikon Df is cleaner in comparison.
6. ISO3200: The same thing can be observed at ISO 3200. The grain definitely appears larger on the D800.
7. ISO6400: At ISO 6400, the Nikon D800 is already losing some shadow details and adding artifacts throughout the image.
8. ISO12800: And at ISO 12800, the D4 still retains plenty of shadow information, while the D800 lost a lot of it. More noise and artifacts appear at pixel level on the D800. Most importantly, there is a noticeable loss of color on the D800.
9. ISO25600: ISO 25600 looks like garbage on the D800 – something I would not want to use at all. And yet the Df still manages to retain colors and details better even at such high ISO values.
10. ISO51200-204800: While ISO 204,800 is extremely noisy and unacceptable for most people, ISO 51,200 and 102,400 could be somewhat usable when down-sampled.
Now keep in mind once again that we are purely looking at pixel level performance here. Once 36 MP images from the D800 are resized to 16 MP, the performance differences shrink quite a bit. Once “normalized” there is not much of a difference from ISO 100 to ISO 6400. Only at ISO 12800 and above the Nikon Df seems to offer an advantage when down-sampled. And obviously it can go even beyond that all the way to ISO 204,800, while the D800 stops at ISO 25600.
I support the domestic film industry,but who would support me?(Google翻的)
