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

Etype. 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.

Lens without zooming feature

①Capture a sharp subject (with a grid pattern) more than 10m apart and adjust the focus ring to the infinity (∞).

②Adjust the adjustable ring of the flange back so that you can capture the sharpest image.

③Fasten the screw of the adjustable ring of the flange back.

Lens with zooming feature

①Capture 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.

②Adjust 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.

③Repeat ① and ② above 2-3 times to match the focus from the ZOOM TELE side with that from the ZOOM WIDE side.
