hello friends I bought a D7100 but I could not see any significant difference between D7100 and D7000 in image sharpness and detail quality point of you related with the so called ' absence of optical low pass filter advantage ' . Have You ?

Right on Mick. The D7100 has been improved in a few different ways and with a different sensor of higher resolution. The new sensor has significantly improved dynamic range. I see the improvement when cropping and mostly when I evaluate my lens resolution tests when viewed at 100%. It's quite a good camera.

Do you have your own measurements to share? Bill Claff's work, DxO and others place the DR of the D7000 ahead of all DX cameras. My own testing confirms that ranking. For DX and 24mpx the D7100 is very good but not better than the D7000 in DR with its very low read noise, and shadow pulling only bettered than the D800. The D7100 has some advantages for sure, in the AF department and cropping options but for image quality the D7000 still beats every camera Canon ever made and 2.1 stops better DR than the Canon flagship 1Dx
In it's simplest terms, the dynamic range in an image is how much detail can be seen between the brightest to the darkest points in that image.
In the earliest digital cameras when you took a picture in bright light, the amount of detail in the shade was mostly very dark with little detail. As sensors and processors improved the amount of detail in the dark areas improved to where a lot more detail is now visible.
Stan, the comparison in dynamic range is in the measurement comparison between the D7000 and D7100 on the DxO site. Look at the measurement curves and not the rating number which is completely misleading.
Overall, there's little to choose between the two sensors, with two exceptions. The D7100 does better with high ISO noise than the D7000 when comparing similar sized prints/on-screen images. The noise grain is finer and less intrusive. If downsampled to the same size as the D7000, the D7100 produces a cleaner image. The D7000 does exhibit less colour noise though..... The D7000 is capable of pushing shadow detail by several stops, and as Stan said, only the D800/E betters it and, ahem, Canon isn't even in the same league with any of its bodies.
I upgraded my D7000 to the D7100 primarily for the more advanced AF and higher resolution for cropping. In some ways, I prefer the 'look' of a D7000 file, although my D800 produces a very similar rendering.
Take a look at high ISO images on Image Resources Compar-o-meter. There is more shadow detail and color at high ISO, say 12k ISO with the D7000. Comparing files, like you say, pulling shadow detail, which is a very common practice in landscape, the flexibility of the D7000 and D800 files are really quite impressive but the D7100 files fall apart quickly when pulling shadow info. One of the reasons cited elsewhere was the apparent RAW NR that kicks in at about 1800 ISO on the D7100. That reduces detail while lowering noise. At low ISO, 100 or 50, the detail is there with the D7100 but the D7000 holds its own in measurements yet still offers a big difference in shadow detail that is recoverable.
If Nikon has gone to the RAW NR beginning with the D7100 like Canon and Pentax have done to get better review test numbers, it also means less flexibility in post processing and large print quality, a key advantage Nikon shooters had over Canon shooters all along. The Sony sensors really have had an advantage since the D90 series over the rival sensors file depth. Canon just gave up, apparently and went overboard with non-defeatable NR trying to get into the range of the D3s and D4 at higher ISO. They do not even try to get into the D800 ballpark in file depth. This whole issue of DR came up since one post claimed a significant improvement in DR. I do not see in actual use and surely not in post processing. In that regard the D7000 is closer to the D800 which is currently the file flexibility king for post processors.

The DR chart from Dxo shows a .2 stop advantage for the D7000 over the D7100. Even if it was the same, the claim that there is a significant improvement is not correct. The low ISO range where subject's were DR is important, such as landscape, is more telling of actual use than at high ISO were it is seriously degraded in all cameras. Stan St Petersburg Russia

Absolutely, no arguments from me at all. The first thing I noticed was the image sharpness when compared to my D7000.
I noticed jumping from a D5200 to a D7100 the effects of the no OLPF immediately, but only when things are perfect. Also, my 50 f/1.8G really makes the D7100 shine for some reason. No idea why, and it's not AF because it does it even in LV, but the images from it are just subtly much better.
The DR curve shows the D7100 ahead of the D7000 at all ISOs except base - but also owning the D5100 and having had one off and on since it was new (same sensor as the D7000), I do not find the DR difference significant between the two. The extra pixels do matter, but not that much - the differences overall are subtle. I've never found a situation where the D5100 produced a significantly better image, overall, than the D7100, but it is noticeably (if not significantly) better in IQ in all aspects.
