Variable Scan Mapping
(VSM)
You can set the scan range for the imaging device
according to the lens attached.
Perform the setting using a recorded image of a
●
white object with uniform brightness.
Caution :
This setting is effective for vignette effect,
●
however it may not be fully effective against
distortion and reduction in ambient luminance.
Perform the setting while taking into
consideration the characteristic of the lens
attached.
When a Micro Four Thirds lens is attached
●
setting for Micro Four Thirds ("80% (MFT)"),
the Micro Four Thirds lens may not perform
optimally.

●
device is set to "100% (Super35)" is displayed

Square frame
Round dotted frame : The image frame of the
Set in such a way that the vignette effect
●
does not spread into the round dotted frame.
3 Press the [USER3] button to check the
brightness.
●
displayed in full screen size.
You can check the vignette effect through the
●
brightness displayed at the four corners and
screen.
It is preferable to get 100 % brightness at the
four corners with respect to the 100 %
brightness at the center. However, depending
on the characteristic of the lens attached,
besides the vignette effect you may also not
get 100 % brightness at the four corners.
Memo :
The values for the brightness at the four
●
corners are estimates. We recommend using
a measuring instrument to obtain accurate
measurements.
