Each lens is optimized for resolution and contrast. While the 90/2 is
fantastic in its range from infinity to macro, someplace along the line the
80/4 will surpass it. Olympus says that that 80 is optimized from 1:2 and
2:1. Somebody with both can do some tests or we can take it on faith as to
what Olympus says.
