If the images are out of focus you can try the following operations:
1. If you calibrate the lens via the DJI RS 4 Pro body, please check if the LiDAR installation distance matches the settings in DJI RS 4 Pro. If you calibrated the lens via the app, you can go to the flange distance adjustment page in the app and adjust the focus until it is sharp.
‌2. Calibrate the lens again. Make sure the subject is in focus at 1 meter and at 4 metres.
3. 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.
4. Longer lenses may also obstruct LiDAR signals and result in images being out of focus. Try changing to a shorter lens and calibrating again.
