Since the Mavic 3 classic lacks the extra tele.  I was wondering if the filters used for a Mavic 2 are compatible with the Mavic 3 Classic ?

Filters for the Mavic 2 will no work on the Mavic 3 Classic.

Hi there. Thank you for reaching out. Unfortunately, the DJI Mavic 2 series camera filter is not compatible with the DJI Mavic 3 Classic camera. In addition, the DJI Mavic 3 classic supports replacing the ND filter, holding the gimbal and camera module, slowly removing the camera front panel, and then replacing the ND Filter. Note that the ND filter has to be properly fitted to avoid a detachment during flight. You may check the available ND filter for the DJI Mavic 3 classic using the link below. Thank you for your valued support.
