DJI H20T - Zoom issue
Updated over a week ago

Are you using the H20T camera?

We have noticed with the RGB zoom lens that the Zoom level set on the camera can change without input from the pilot. This happens when swapping batteries, but it can also happen mid-flight.

When flying with this camera, please ensure that you are monitoring the zoom level set at all times to ensure that you do not have any problems.

When the zoom level changes, there is a drastic change in the overlap, resulting in a large amount of missing data and most likely a re-flight for that operation.

​​Please be aware of the possible issues with focal length when resuming the mission or swapping the batteries.

How to avoid such an issue before it's too late?

Use the photo checker in the field - or as soon as possible.

The photo checker will notify you if your data has different focal length values. If yes, the data will be rejected as we cannot use.

βœ… Expected values: 10.14 mm

❌ Rejected values: 6.83mm / 25.39mm

The validation check will be done as well when uploading the data.

How to prevent it?

Please Check the zoom settings at all times when flying. You can adjust your settings on the screen in the flight app.
