D600 vs D7100 same exposure (or at least close)
Don't shoot the messenger, I didm't buy the D7100 to be a lowlight monster!
Thanks. The comparison with the D600 makes it clear the D7100 is performing on par with the D5200 with respect to banding. Btw, don't dimiss the D7100 for low-light - if you shoot that same scene at ISO 3200 you'll likely see none of the banding. The banding is unique to low ISO and is dithered out by the ISO gain logic in the sensor complex.

Well, one thing that's no surprise is that there still is no full rotation 180 degrees with the 24mm pc-e tilt-shift lens. Close enough to work however.
Also, it must be a new trend now to only put the lcd covers on the higher end camera as was stated before, there is none in the box, nor a way to snap one on. Oh well.

ISO 3200 2 stops underexposed.
Yep, much better. And for a fair comparison with your ISO 100 image, you'd want to shoot that at ISO 3200 at 0-stops underexposed. Here's a wide-DR ISO 12,800 image from a D5200 with no luminance noise reduction. Notice there is very little banding; what little there is can be seen only in the deepest shadows, which represent the exposure equivalent of about ISO 51,200. The magenta cast creeping up at the bottom of the frame is due to amplifier glow, which is present on the D800/D600 as well. The D7100 likely performs identically to the D5200 in this image.

Woo-Hoo! Just picked up my new D7100 (body only) this afternoon thanks to the good folks here at Stewart's Photo in Anchorage. Will tinker with it a bit later this evening, but was wondering if anyone has had a chance yet to check whether the Back-Focusing issues of the D7K are gone with this model?

Here you go Michael. the second shot says 1 ev over 6400 (h1) not sure why it's not showing in the exif.

Those high ISO shots look very promising indeed. Thank you so much, rich.

I have a one ton dually that I call my sports truck.
My main concern about the D7100 is the grip.
The D7000 was fairly comfortable but the D600 pinches my fat fingers.
Hopefully, I will have one in my hands tomorrow.

While i am waiting at least another week thought i'd ask those who upgraded from the D7000 AND had to adjust your lens if with the D7100 you've made any changes, like setting it back to 0!
My take from the early adopters is that QC is holding up .... so far.

ISO shots look VERY promising. A fellow on facebook posted up a shot at 3200 with some light and it looks quite clean.
I saw some ISO12800 and 25600 shots on the internet that were so amazing that I thought they must have been processed.
Can't wait to get my "Hands On".
Question is: the grip is just like the D7000 or the deeper/tighter D600?

I've done a bunch of back-to-back testing now with the D300 and the autofocus is, in the most extreme cases, in a completely different league from the D300 - almost astonishingly superior. In all cases, though, it's just plain better. Faster, locks focus more reliably. I don't know if this is the new sensors that are more sensitive (down to f/8), or if it's tweaks to the CAM3500, or if it's more processing power, or a combination... but this is going to be a measurably better birding camera because of it. Especially for those of us who can't afford a 600mm f/4
I have nothing particularly good to show - I spent some time at a lake near work this morning playing around but there are too many people who use the running path to stalk the birds much, and the Great Blue Heron who lives there did not show up. However, the high ISO performance is at least a stop better than my D300, and probably closer to 2 stops.
The bluebird was pleased with his breakfast, in any event.

That looks pretty good to me. what lens did you use on that shot? (and 900 ISO)
It's my 200-400 f/4 with a 1.7x teleconverter on it.
Auto-ISO, hence the weird value. That's something else I like: the "auto" minimum shutter speed for auto-ISO that adjusts the minimum shutter speed to account for focal length, with a weighting that you can adjust. Mine is weighted one tick slower than "normal" which seems to put the shutter speed right around the 1/FL rule for the physical focal length of the lens. "Normal" seems to take the crop factor into account and adjusts the shutter speed for the 1/FL 35mm equivalent. This isn't new to the D7100, but it's new to me.

and, what crop mode?
Let's see some really high ISO pictures and tell us how well the AF works in the dark.
I should have put it into the crop mode but I didn't. That image is fairly heavily cropped.
No good high ISO photos from this morning, but I did a lot of autofocus testing and it is a whole lot better than the D300 for low light. By which I mean, I tested in many scenarios where the D300 would simply not find focus - very dark shadow areas in the trees before the sun came up - and the D7100 focused every time. I'm really, really pleased with the performance improvement.
edit: Okay, here's a lousy ISO3200 photo from this morning, since you asked. The little guy wouldn't come out of hiding so I just snapped this when he poked his head out - it was before the sun had gotten over the trees. Dark exposure, very heavy crop, straight out of the camera... this is pretty much a worst-case scenario.
Not a great example, but the OOF areas are a lot less noisy - and a lot finer grain to the noise - than my D300 typically is.
