Re: D7100 seems significantly better than D7000

I had a look at the RAW files from Focus Numerique.

Just downloaded the images for ISO 800, 1600, 3200 for the D7000 and the D7100. The EXIF data was changed in the model field from "NIKON D7100" to "NIKON D5200" which allows Lightroom 4.4 RC to process the images. We can't be sure that the D5200 profile used by Lightroom is correct but it works temporarily and any proper support can only be better.

White balance was adjusted, sharpening 45, 0.7, 70, 20. D7100 files also had luminescence NR 15 applied. The D7100 files were downsized to the same size as the D7000 files (4928 on the long edge).

The D7100 files seem significantly better at these higher ISO's showing less noise at equivalent size and more detail - possibly around a stop or so. Interestingly the D7000 files show more moire/aliasing than the D7100 files. Any banding that has been reported is not something that I can see - if it is there it is very hard to detect in any normal use, or requires such a push that the image would degrade so much any way.

The images need to be looked at at the same size for comparison - I have downsized the D7100 to D7000 size. Please note that the D7100 files will report D5200 as model:

D7100 ISO800

D7100 ISO1600

D7100 ISO3200

D7000 ISO800

D7000 ISO1600

D7000 ISO3200

To me, the D7100 looks around a stop better than the D7000 - that is the D7100 ISO1600 looks as good as the D7000 ISO800, etc.

While the FN images leave a lot to be desired, the differences between the two are too significant to be bad testing - I don't think they are close, the D7100 is a significant improvement.

(Luminescence NR always reduces detail - there is no free lunch - so applying that to the D7000 files would reduce detail further)

Thanks for the good job. Are you sure you have the same settings on both? I guess you left the default chroma NR ON (usually 25 value), since these show almost no chroma noise. The difference here is much more than I would expect after resizing, more like 1/3 to 1/2 stop, after some comparisons of D5200's and D7000's files. I also recall that on images from this site the D5200 looked better than on images from DPR and IR. We have to wait for more samples.

Well in these the D7100 significantly better in noise, and resolution as might expect, but there's something funny going on with the noise aspect of these shots. I mean they're a little too good in the comparison I think.
