What is the camera filter ring diameter size (in mm) P3 Pro? Plan to replace standard UV filter with variable 8 -stop ND during bright, sunny days. ND filter estimated weight is around 50 gms.

Hi there. As electronic products are affected by technological developments and changes in usage requirements, each generation of products has a fixed life cycle. In order to continuously provide you with premium product and service experiences, DJI regularly optimizes resource allocations to promote the development and application of new products and technologies. Therefore, we have decided to stop providing support services for the Phantom 3 Series and its accessories starting on January 5, 2023. We're sorry that the services for this product have been suspended currently and relevant technical support and after-sales repair services cannot be provided. Thank you for your understanding.

I understand but this is just a simple question, ring size diameter. Had you included it on the camera specs sheet, no queries would have arise. Surely, info is somewhere in your P3P dbase.

At any rate, thanks.
