The ND/PL filters are slightly taller.
There is manufacturing variance on the Mavic Camera, there is manufacturing variance on our filters.
When both variances are on opposite ends of the spectrum, they can slightly hit the gimbal (physical interference) causing error codes.
The Straight ND's are not as tall and there is no physical interference, which is why you will find a few customers are seeing some problems with the ND/PL's.
The current cure for users with Mavic cameras on the far end of the variance spec, is to use Straight ND filters, or let us work with them to get a set of ND/PL's that is within spec of their specific camera.
The ND/PL glass can not be put into the Straight ND frame because the glass is too tall.

I appreciate your response. I really would like to have a set of these Cinema Series Vivid Filters. Would you be open to a discount?
