Analog box camera is out of focus

Applies to: HCB-7001VP

Issue Summary

Sometimes, after installing the lens-mounted camera, the focus cannot be adjusted with the SIMPLE FOCUS function. Even when moving the lens all the way in Manual Focus mode, it remains out of focus.

When a BOX camera is used with a separately sold lens without performing the Focus Initialize function, the lens focusing operation alone may result in a misaligned BFL (Back Focal Length) and lack of focus.

Resolution

When performing the Focus Initialize function, adjust the sensor position (near ↔ far) to execute the BFL adjustment.

When installing a BOX camera (Simple Focus specification), couple the lens and then perform the Focus Init operation to automatically adjust the position of the camera sensor before use.

To focus the lens:

1. Install the lens.
2. Perform the camera FOCUS/INIT operation.
   
   
3. Run the SIMPLE FOCUS function.
4. Confirm the screen focus.
