Selection Of A Lens File - Sony F23 Operation Manual

• If the white clip function is in use
As the white clip function limits the level of output video,
the dynamic range specified for the input video may not be
obtained for video output.
• If "Select FPS" is ON and Compensation is in Gain
mode
The value of the dynamic range may decrease by up to half
at maximum, depending on the FPS settings.
Memo
Why the ISO sensitivity is defined for 20% input
Defining the level of gray scale of 18% reflection rate for
the ISO sensitivity on the linear curve (defining with input
signal) permits you to use the values as the absolute
reference for proper gamma conversion in postproduction.
In addition, defining the output for 20% input with ITU-
R709 so that it becomes the reference code for Cineon
curve allows high compatibility.

3-2-7 Selection of a Lens File

With this camera, the compensation data for the mounted
lens can be adjusted in Custom mode and registered in the
built-in memory in lens files (max. 64 files in total: 32 files
for serial lenses and another 32 files for non-serial lenses).
You can invoke the compensation data for the mounted
lens by merely selecting the corresponding file.
Lens file selection page
LENS:1
No Offset
On the first line, select the number of the lens file.
(If a serial lens is mounted, its name will be recognized by
the camera, and the corresponding lens file will be
automatically invoked. In such a case, the file number is
always set at 33.)
On the second line, the lens-file name corresponding to the
selected file is displayed.
The selected lens file will be retained until a new lens file
is selected. As long as the same lens is used, further
selection of the lens file is not required.
Note
All the lens files are named "No Offset," with all zero
settings at shipment. File registration and modification of
data in a lens file must be performed in Custom mode.
For details on the lens files, see "Chapter 5 Storage and
Retrieval of User Setting Data".
