Preview function
When you press the preview button, the viewfinder shows the actual depth of field (the
distance from the nearest to the furthest point of perceived “sharp” focus) in a picture,
with the selected aperture value.
Exposure compensation
In some situations, you may get better results if you manually compensate (adjust) the
exposure value set automatically by the camera. In many cases, bright subjects (such as
snow) will turn out darker than their natural colors. Adjusting toward + makes these
subjects closer to their real shades. For the same reason, adjust toward – when shooting
dark subjects. The exposure can be adjusted in range of ±5.0 EV. Center weighted
averaging metering (
) or spot metering ( ) is recommended for exposure
compensation. The EV step interval can be selected from 1/3EV, 1/2EV or 1EV.
Metering mode
There are 3 ways of measuring the subject brightness: Digital ESP metering, Center
weighted averaging metering and spot metering. Select the most suitable mode
depending on the shooting condition.
Digital ESP metering ESP : The camera meters and
calculates the light levels or light level differences in the
center and other areas of the image separately.
Recommended for shooting under conditions where there is
high contrast between the center of the screen and the area
around it, such as when shooting backlit subjects or under
excessively bright light.
Center weighted averaging metering : This metering
mode provides the average metering between the subject
and the background lighting, placing more weight on the
subject at the center. Use this mode when you do not want
the light level of background to affect the exposure value.
Spot metering : The camera meters a very small area
around the center of the subject, defined by the spot metering
area mark in the viewfinder. Use this mode for intensively
backlit subjects, etc.
