On an actual subject that occupied a much smaller area using one T-32, I had
the opposite results with an OM-4 vs OM-2N. In my case, the OM-4 would not
blink from f/11 to f/22. This brings about several questions. Is the OM-4
identical to the OM-4T in this respect? Can the OM-2N pick up a smaller
subject better? Do individual cameras vary? I know MY OM-4 was terrible. As
the OM-4 was of no advantage over the OM-2N for my use, I sold it and
switched to an OM-2N.
