Its been 8 months, anyone have any input on this question?
I will have my observations to input, as soon as I can find a minute to compare my D7100 to the D800E. I have only taken about a half dozen with the 800, so far and it does "seem" like there's some difference. I suspect the 7100 will be designated for itty-bitties and the 800 for larger subjects. I am very eager to compare the two.

Compare this post shot with my 5D Mark II full frame: http://www.uglyhedgehog.com/t-253014-1.html

To this post shot with my 7D Crop. I just could not get the crop to come in sharp no matter how hard I tried with the same 100mm lens: http://www.uglyhedgehog.com/t-252379-1.html

Apples to oranges but for me the difference was amazingly clear. (pardon the pun.)
I use the full frame for macros and the crop for sports now.

The D7000, tokina 100mm lens and Diffused Speedlight is extremely sharp when used properly. I missed the focus on the outside edge of the eye, but the rest is very nice for such a small subject and I'm not on the perfect focal plane as well. Just one of thousands I've taken. I'm sold on FF as well but not for lack of sharpness from my crop sensor camera. Proper Lighting is More important than camera or lens

more and more i'm getting the impression the contrast range is critical in obtaining a sharp stack.

I'm a lazy type of guy when it comes to certain things. I have yet wrapped the inside of my tubes with any thing to dampen the light traveling back into the lens and sensor. When I photograph against reflective materials like buildings, sun light leaves ect.. I get a very contrasty photo. If I had the room I would use lens hood to help. Not sure in your set up but make sure you don't have light traveling back on your lens. On another note using the Nik software I use the contrast control slide on all of my finished photos, my best friend to bring out the detail, but I use it selectively and at different levels for different parts of the photo.. To much and it robs detail, just right and it brings it forward, also darkening/selectively/ Just a hair will often bring detail forward as well. I still do not use sharpening only contrast control.

I managed only a few quick shots to compare the DX (D7100) to the full frame FX D800E. I shot mirror up (live view) and used the remote on the 7100 but, couldn't do so with the 800. I took a few shots with and without the Raynox250. I also shot only jpeg fine, neutral, and with no PP at all so, these are SooC. I think these are slightly under exposed. I also could have used more light on the subject so I could see what I was doing. Both cameras settings were: ISO 200, 1/200-sec at f/16

I used these butterfly wings because they're not flat and at least some part of them should be in focus, no matter if "I" don't get the focus just right. Scan around the image on download to examine. I'm not certain I see much difference under these conditions which is what I suspected. I think as time goes on, close cropping and various subjects will tell more.

I wouldn't expect much difference in IQ between the 7100 and the 800e and say the 7100 versus the 610. Pixel size and density of the 800 falls midway between the other two sensors:

Camera: 7100 800e 610

Pixel Pitch: 3.90 4.87 5.95

Pixel Density: 6.59 4.22 2.83

(mp/cm2)

All that noted, the 800e at higher magnifications, might resolve more details due to the lack of an AA filter.

not sure how you arrive at pixel pitch.
I'll say two 'hail marys' and an 'our father' for you if you can come up with a column for the canon 70D.
Pretty please?

Looks Like the D610 has the largest Pixel size, is this better?? More info per pixel, better resolution

Not better, just different. Larger pixel size collects more light, a larger sampling if you will. Like a bucket in the rain versus a cup. Smaller pixel size resolves finer details. At 1:1 I don't think we can see it but at say 20x I believe we can. Running stacks with my Olympus E-M1 at 20x versus my 5D-III, I believe I can see a difference in resolvable detail. Nothing scientific mind you, just the old eyeball verification.

The D7100 also does not have the AA filter

anyone else have the feeling longer lenses couple better with the high density sensors?

An interesting thought and first thing that comes to mind is it would seem so. Have to do some research on that.
