The meter is so accurate because it's measuring *during* the exposure
rather than *before* it, so the meter can measure in lower light for the
same sensitivity. At 1/60 and longer, it measures the light bounced off
the film.
There's a tradeoff, though, and that is that some films don't have the
"right" reflectivity. I recently ran into this problem with Elitechrome 100
(verified by grey card tests in 2 OM bodies). Even more worrying is that
film would not be QA'd for this, and it might vary from batch to batch.
Given the choice between accurate, repeatable exposures down to 2s and a
chook raffle down to 2 minutes, it's not surprising that Olympus is the
only manufacturer persisting with OTF for anything other than flash. Most
people don't do low-light photography and blame themselves when they have
flash problems (flash traditionally being a bear). But a large number
of people do shoot at 1/15s.
I will post the methodology and results for my Elitechrome test
in a separate article so that everyone sees it.
