Hi rww11
Maybe sharing the two images and the conditions for each might be helpful in understanding the differences between the two setups e.g.
1) Are you comparing JPEGs right out of the camera or Raw images put through a Raw processing? JPEG images are typically not processed the same among different camera bodies
2) Are the images taken from the same position of the same scene to maintain the same perspective? (your prior post indicates that you are)
3) Assuming #2 is true, to get the same angle of view for the two images, between an FX and DX format camera body, I would assume you using a longer lens (or lens setting on a zoom) for the FX body (1.5X longer for Nikon FX bodies than DX bodies)
4) Given #2 and #3, to create the same depth of field, you would need an Aperture setting 1.5X that used on the DX body e.g. if the DX lens setting was set at F 1/4 then the setting for the FX body would need to be F 1/6
5) The of course with #2, #3, and #4 then either shutter speed or the ISO would need to be changed due to the aperture change to have the same exposure.
I would consider the above to be a starting point to make sure there is the same perspective, angle of view, depth of field, and exposure for the two images. If the above steps were not taken, then there would some mismatches in some of the characteristics just mentioned.
Even with the above steps to match characteristics of the shot, you certainly could have some differences to consider. Those differences can have a variety of sources which could be discussed (and some already discussed such as lens quality)
Again, it would be helpful to see the images in question and the information about the lenses and settings (focal length, aperature, shutter speed, ISO for both images)
Hope this is of some help and I am pretty sure the parameters I set to match characteristics are correct (though I did do that from memory).
