The lighting, ISO, shutter speed, Fstop, and focus used are constant in all testing modes. I also use ND filters in order to slow the shutter down. The goal was to isolate the shutter speed with a solid mount, that still shows shots that are blurry due to mechanical "noise". This is how I was able to Isolate the shutter speeds between 1/125 and 1/2. The lens is plenty sharp for determining this since it is clearly visible between a LiveView shot and a EyeView shutter shot.. Thank you.
Except there is a flaw in your thinking. Liveview still uses the shutter, so you are introducing the difference somewhere else. When you switch from AF to MF that might be enough to make the differnce you are seeing. Liveview and mirror lock up are functionally the same when it comes to taking a photo.

Your samples all show one of two or both, camera shake and/or misfocus. And just to complicate things you added a filter to the lens. If you want to find the best qualities of a lens, there can be no filter. IMHO, of course.

Agree with the idea you can't do this & use a filter, even a very good one. What brand & model are you using?

In live view, the second curtain of the shutter can make the shake. Mirror lockup mode you have both the first and second curtain. Normal mode you have the mirror, the first and the second curtain that can make the shake.
You have already proven with your second image that your normal AF focus correct, so the other two pictures are unsharp because of shake.
