Me too but someone will come along and complain of "horrible noise at ISO 100".

Definitely better than my D300s, that's for sure. Just wondering how it compares to the D600, as one of those two cameras will be my next.

Hi Slayerrizer, in jpeg alone, can you tell a big difference in sharpness/detail between let's say your D5000?? Do you think that without the AA filter you are seeing something new?
Also, what else do you like/don't like about the camera? How is the AF system, have you had a chance to experience with that all night, what are your early thoughts on that? When you focus on something and you leave it there, can you tell if the focusing is toggleing back and forth or does it feel like is really accurate and locks on very well?

He doesn't own the D7100 yet. Read all his post.

Only very-very limited banding
a lot better than D5200 sweeeet...

sweeeet...I have D600 cameras. I expect a very little more resolution at base ISO for D7100, but the overall image not to be as clean as with D600. The resolution advantage will be lost at medium ISO and D7100 will have less resolution at high ISO because of noise which need to be cleaned. D600 DR is also better.
I am curious about the video capability. I suppose that can not match the D600 video quality at ISO higher than 2000, but can be very good below ISO 2000.

At one stop lower ISO the D7100 should be dead even with the D600 for SNR at higher ISOs and have about a half stop DR advantage. However, there is no way with any existing lens that the D7100 will rival the D600 for resolution.

Looks impressive to me looking forward in getting one - bit of shame with me losing one of my D7000's for it.
Finger's cross for some good QC with all people's D7100's.....

Why not? Especially with no AA filter, same pixels at a higher magnification, I would expect the D7100 might be better.

I was thinking the same, why not? I've got a D600 and the files at 100% look like crap compared to the 800E because of the AA filter. I think the resolution might be better given the same# of pixels.
I'll admit that if Nikon can squeeze anywhere close to the same high ISO performance and dynamic range out of the 7100 as the D600 it would be a minor miracle but it seems like with every new body/sensor we're seeing performance we all though impossible a year or 2 ago.
The 85mm f1.4 G is a highly resolving lens. dxomark tests this lens at 10 P-Mpix on a D300s, just 11 P-Mpix on a D7000. However, when we move from 12 MP to 16 MP in FX resolution inceases from 12 P-Mpix on the D3s to 15 P-Mpix on the D4. On the 24 MP D3X we're looking at 19 P-Mpix, and the D600 won't be lower. The D800? 22 P-Mpix. What we're seeing here is that as pixel density increases the relationship between pixel count and resolution falls away from 1:1.
This would be a major miracle and will not happen.
Unfortunately, my D300 and D300s will still lag in terms of DR and low light ISO. One caveat, however: supertelephotos like my 300 f2.8 VR and 500 f4 AF-S have more resolving power than the 85 f1.4 G. Shot at wide apertures they may be able to resolve much of the 24 MP.

Samples at 64 & 128...well, maybe slightly better than the D7k, but not a whole lot. Not worth spending on for that aspect alone. Wonder how good the AF is....hope that is a bigger improvement...

No noticeable magenta nastiness at 25,600 = win! Hated that about my D7000. The ability to retain near-accurate color at the highest ISOs is definitely better than the D7000.

Seems like the D7100 has the same sensor as the D5200. Only 0.1 stop better low light/high iso. What a shame. Seems kinda dumb to only be 0.1 stop better. I guess that's fine if your birding or taking landscape shots. I was hoping for a nice bump in ISO so I wouldn't have to purchase another D600.

The improvement is actually much greater but you have to dig a little deeper into the DxO numbers. It's true that the SNR @ 18% is about the same, but the DR on the D5200 is 1 stop greater at High ISO due to a significant decrease in read noise on the D5200/D7100 Toshiba sensor, which translates into a 1 stop improvement in shadow noise at High ISO, and shadow noise has a big effect on the perceptual noise improvement. At 2.133% signal, the D7000 has an SNR of 3.7db, while the D5200 at 2.289% signal has an SNR of 7.2db, and 3 db is equal to 1 stop.
