Sure...I would be happy to look at a sample. I tend to think based on what you have said maybe the focus plane is off somehow, as a previous poster said. In my experience the 54M easily out performs the 5DMKII and even the D3X at base ISO. (Not looking for a debate here, this is my experience)
I hope you are right, because that would save me going through selling whole kit ( camera, lenses and the back ), and having to buy new camera.
