Is camera shake a bigger issue on Full Frame cameras?

Looks pretty sharp to me. Any VR involved? Also, here is a full size portrait from D750.

Here you go, handheld D800 wide open keeping the speed up using the corresponding ISO.

I bought the D750 and have been taking some shots around the neighborhood and at home. I am finding that, on close inspection, following the shutter speed = focal length rule is not sufficient for truly sharp images. Indeed, even doubling the shutter speed does not seem to do the trick. I also notice that of all the sample pics I've seen, its very hard to find one that demonstrates the camera's sharpness. I realize that there are many factors that contribute to sharpness, but when I stand 8 feet away from a small object with a 50mm lens set at f.28 at low ISO and 1/50th of a second, and then zoom in to the LCD at 100%, the small object is not tack sharp. I would like to see a sample pic that shows incredibly sharp detail at 100%. That's what I expect from this camera. Is the full frame format the culprit here? Is VR a must? Any thoughts?
Is there any possibility the issue is not sharpness per se but depth of field?

Remember your DOF is not about %33 shorter than a DX (assuming you've just moved up from a DX).

Whereas on my DX camera the 501.8 focused on the tip of the nose would have the rest of the face in focus, on the FX the rest of the face is noticeably starting to blur.

I've just made the leap a week or so ago to FX and I find that the depth of field is far more exaggerated than I thought it would be and went through the same process wondering if it was me, the camera, the screen or the lens.
 
I don't think you understand the premise.

This is about the idea of whether or not a "high megapixel camera" (like the D8x0/e) is more susceptible to camera shake than a "low megapixel camera" (like the D3, D700, or maybe the D6x0 or D750).

If you believe the answer to that premise is YES, that a high megapixel camera is more susceptible to camera shake than a low megapixel camera, then you have to explain why you believe that when the difference in the size of the pixels between the cameras is of the order of 1/1000 of 1mm.

I believe the answer to be NO, and that all cameras are susceptible to the same movement, and anyone who think they can see a difference is imagining it.

This has nothing to do with how you display the relevant images, or to the degree you crop them, or the size you print them out. That is completely irrelevant to the question being asked.

I understand it perfectly fine, thank you. You on the other hand are stuck in an incorrect premise and refuse to work through it logically with an open mind. For some reason you are fixated on the physical size of an individual pixel yet cannot complete the picture (see the pun?) around how they are ultimately used.
The physical size of the pixels is the only difference between the cameras, and it is the pixels that capture the image. Any difference you claim to see on screen, or in print, or anywhere is a direct result of what is captured by the pixels. See?
I see no point in a dialog with someone illogical and close minded so I'll leave you with a quote from Nikon to consider:

"At the high resolutions offered by the D800/D800E, even the slightest camera motion can result in blur."
That is 100% true for 100% of cameras.

The bit you're missing is *why* that is the case (if it is, personally, that's just marketing). What is the difference between the D8x0/e and any other full-frame cameras? Or cameras with other format sensors?

Yes.. we're all looking at the output of the sensor not the sensor itself.. aren't we?
Yes, you are looking at the output of the sensor. Therefore what the sensor captures, and how, is somewhat important, don't you think, when the entire premise is about the difference between sensors of different sizes and the pixels that make them up.

so is bigger or isn't bigger issue. can somebody summarize?

Sharpness at a pixel level you speak of is related to several things. One very important thing is subject motion. This focal length or double focal length rule goes out the window when you consider a subjects motion relative to the focal length they where shot with.
