| The exposure meter is located on the pentaprism, just above the viewfinder, so is impacted with a focus screen change.
And the LL80 is, AFAIK, based on the same fresnel lens formulae as the original focus screen, and so will suffer from the very same problem... (and, on an aside note, the LL80 is not a "rule of thirds" screen as the LL60, but a less useful "rule of fourths" screen). |
