Adjust the back focus

The back focus of a camera is predefined by the
factory default. However, some models are out of focus
depending on the lens type. If your camera is out of
focus, follow the instructions below to adjust the back
focus. The following is the procedure used to set the
proper back focus point in fixed focus lenses.
C direction
Lens without zooming feature
1. Capture a sharp subject (with a grid pattern) more than
10m apart and adjust the focus ring to the infinity ( ∞ ).
2. Adjust the adjustable ring of the flange back so that
you can capture the sharpest image.
3. Fasten the screw of the adjustable ring of the flange
back.

apart and adjust the zoom in the TELE (zooming)
direction as possible and also adjust the focus ring so
that you can capture the sharpest image.
2. Adjust the zoom in the WIDE direction as possible and
turn the adjustable ring of the flange back so that you
can capture the sharpest image.
