<Metering Range>
This
chart
shows
the
relationship
of
the
aperture,
shutter
speed
and EV value, and you can check the metering range of your
lens on it. If you are shooting with an ISO 100 film and F1.4
lens in the center-weighted average light metering mode,
for example, first find “100” on the ISO column in the
dÉ,
SE Lens Aperture table and locate “1.4” and “16” in this
ELLE DD row (the minimum aperture of the Planar T* 50 mm
A ER SC S is F16). Then, follow the corresponding oblique
5 5 5:6 OS SEH lines and find their intersecting points with the
KEREKERE KY -— vertical line (EV) and horizontal line (shutter
