As I recall the F4, N90 and other medium to high end bodies would give you matrix metering as long as you used an autofocus lens like a D lens but if you set it to matrix and used a manual focus lens, AI or not, it would default to center weighted metering. I never noticed much difference in the two and generally don’t worry about it now be it film or digital. That’s the nice thing about the F2. One meter mode, center weighted, and with a little attention you know when it’s wrong and how to adjust. Rick H.
