I guess the best test would be with slide film to see if they are actually
over or under when the camera says they are. The way the Japanese designers
explained it to me: "If you want 8 spot readings, then some other feature
may be down graded, like ttl flash."

| I had been wondering about this, so thanks for the explanation, Tim. I was
| getting the impression somehow that the 2N was actually "better" at TTL
| flash than a 2S. But these are really statements more about the display
| than about the exposure itself, is that correct to say?
