I assume that you pronounce your name Doubt-er, as you have sown seeds of doubt. I have been frustrated at getting one eye out of focus, even at f2.8. With the Nikon D90 at 85mm and f2.8, standing 8 feet from the subject there should be about three inches in focus. And Marilyn is nearly perpendicular to me. Perhaps I should have this camera and lens professionally calibrated to see if there is a problem.
