I sold the 90 AA and bough the 90 pre-ASPH and a Nikkor 85/2. The 90 AA was sharp right out to the corners at medium and long distance, but not close up. To me sharpness isn't everything and I was shooting people with it, not architecture. The immediately preceding pre-ASPH 90 is kinder to people but at a stop or two down is absolutely sharp through the distance range. A wonderful lens.
