BACK FOCUS ADJUSTMENT

1. Level the camera on a stable surface or tripod.
2. Set a focus chart at a medium distance from the camera. (5 to 10 feet)
3. Attach a medium length prime lens to the camera, (50 to 75mm) and set the lens focus to match the

appropriate distance the camera is away from the chart.

4. Using a 5/32” Allen wrench, loosen the two (2) screws on the focus ring near the front of the camera.

5. Adjust the camera focus ring until the focus chart is in focus.

NOTE: The MAGNIFY (Image Zoom) function of the camera can aid with visibility, and may help
achieve more accurate results.
