Metering method
There are three metering methods available. All three are reective methods (measuring the
light reected o various selected parts of the subject according to method) and are through
the lens (TTL). These have the following designations (with their respective LCD symbols):
— Average
— Centre weighted
— Spot
Average: Commonly used for ‘average’ light situations where there is no particular dominance
of light or dark areas across the tonal range. Takes into account approximately 70% of the
image seen in the viewnder.
Centre weighted: Emphasises the central section of the focusing screen equivalent to approxi-
mately 20% of the image. This provides a balanced assessment and is a typical choice where
the main subject is in the centre of the image.
Spot: The sensitive area is equivalent to approximately 2% of the image area (the central spot
on the viewnder screen). Any parts of the image outside of this area will not aect the expo-
sure reading. This provides a very accurate measurement of specic tones.Typically used in the
zone system and similar light measuring situations where maximum control is required. Also
excellent for tonal comparison measurements. The spot mode can display ‘zones’ instead of
EVs in the viewnder LCD( see Camera Options).
Average (45 x37mm) ~ 70%
Centre weighted (23x20mm)
~ 20%
Spot (diameter 7.5mm) ~ 2%
