You can try the following operations:

1. Calibrate the lens again. Make sure the subject is in focus at 1 metre and at 4 metres.

2. A hood or matte box attached to the lens may obstruct LiDAR signals and result in images being out of focus. Try removing the hood or matte box and calibrating the lens again.

3. Longer lenses may also obstruct LiDAR signals and result in images being out of focus. Try changing to a shorter lens and calibrating again.
