Any quoted "resolution" that does not specify MTF at that resolution is misleading and tells you nothing.
The graph shows that at 3200 vertical the system has only 20% MTF which is useless, the industry standard is 30% and even that's being generous.
At 30% MTF the camera is only good for about 2200 vertical which is about half 8k for an 8k system. Only very high contrast details have a chance of being visible at 30% MTF, anything less will just be a blur to the eye.
This is an entirely normal and predictable response for an 8k digital camera, the theoretical ideal response is only slightly better and is also shown on the diagram.
MTF tests are done under ideal conditions with everything perfect, real world performance is rarely ever going to be that good. Even slightly imperfect focus due to focus error or depth of field and motion blur result in much less resolution than a perfect still shot under ideal conditions with no motion.
Please provide links that show the "industry standard is 30% MTF."
