Adjusting the back focus

The back focus of the camera is adjusted at the factory before delivery but
some lenses can be out of focus depending on the lens type. In this case,
you have to adjust the back focus. The following describes how to adjust
the back focus of the lenses.
In case of the lens with no zooming function
① After exposing the camera to an object with high resolution (like
a dart-patterned image) at a distance of more than 10m, set the
lens focus ring to infinite (∞).
➁ Adjust the Back Focus Control Bar until the object is of best quality.
➂ Fix the screw of the Back Focus Control Bar.
In case of the lens with zooming function
① After exposing the camera to an object with high resolution (like
a dart-patterned image) at a distance of 3 to 5m, fully rotate the
lens zoom to the TELE direction. Then adjust the lens focus ring
until the object is of best quality.
➁ Fully rotate the lens zoom to the WIDE direction and adjust the
Back Focus Control Bar until the object is of best quality.
➂ Repeat step 1 and 2 two or three times until the focuses of Zoom
TELE and Zoom WIDE are clear enough.
