# LR1 Lenses and Expansion

### Default Configuration

By default, the LR1 Payload comes balanced and tuned with the Sigma 24mm F3.5 lens, which covers most mapping applications. However, the gimbal can be re-configured with other lenses and external modules for other use cases!

### Lens Settings

All compatible lenses will have settings to change the focus mode and adjust the aperture. For the LR1, which comes with a Sigma 24mm lens, we recommend you set these both to AUTO.

While it may be tempting to set these manually, setting the focus and aperture to AUTO will expose these settings to be modified any time in AMC.&#x20;
