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
E
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.

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.
Lens with zooming feature
① Capture a sharp subject (with a grid pattern) 3-5m 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.
③ Repeat ① and ② above 2-3 times to match the focus from
the ZOOM TELE side with that from the ZOOM WIDE side.
