Look at your EXIF data, if you are shooting over 800iso for the majority of your best images then a cropped ff image will give as much detail as an uncrossed crop sensor image.

People like Keith Breazeal who posts lots of air racing from Arizona, with it's glorious light, will benefit from the crop sensor or using the 5DSR as that light will realize the advantage of those smaller pixels. People shooting in low contrast cloudy conditions will not, they will benefit from the more assured AF and response time from the 1DX series cameras.

You do not need a TC to equal the resolution results from a cropped full frame sensor and a full crop sensor on same generation cameras when shooting at 800iso or higher. This has been proven and illustrated many times.

I mostly shoot around 100-200 iso if weather permits, if not it might go up to approx 400 max..

I have a 1D IV, a 7d II and a 5DsR.

If I want to shoot action, a flying plane maybe, I would use my 1D IV for its speed and af.
If I want sharp and pixels I go with the 5DsR.
If I want to shoot a movie or need a paper weight on the desk I go with the 7D II.
There is no make believe crop / mm advantage with the 7D II vs the 5DsR.

  • How you relate to the issue, is the issue.

Your current camera has 175 pixels/mm. EOS 1D X has 144 and mark II 152 so you probably lose detail EOS 7D Mark II might be better. It has pixel density of 244 pixels/mm.

I would say IQ is more than photo sites/mm. The quality of the photosites matter

Yes.  Seems obvious but I guess it is not.
