Hello everyone, here is a DIY solution for the problem. Main issues here are the OP glass is very soft and many filters do not have some soft material between the lens and the filter. PolarPro has it, but it still dangerous because of tiny pieces of dust and other garbage that may be between a filter and the lens. So, just take a common phone screen protector, cut it with scissors or a paper knife, make a circle hole in the center and attach it on the OP lens. It makes a space between the lens and a filter and a filter do not produce any scratches then.

But is there a rough quote on the cost ?

Check their online price list.  It was mentioned the other day in the battery replacement thread.

how can I find the price list ?

I have same issue with scratched lens... i take risk and polish lens. After 4h of hard work and no more scratches. Of course  the coating is off, but no differences in video quality

I fixed the problem by sending it in to DJI support
