I'm thinking of buying some new ND filters but as i'm new to flying drones i'm not sure which type to buy. I like the idea of advancing my photography by the use of airial photography, landscapes, buildings, churches and that type of thing. I'm using the phantom 3 pro.

I have a P3P as well. I have a few and love them. It's pretty sunny here in Florida usually and my CPL filter really makes for awesome footage when at the beach or any water. I have a few ND variations but the CPL is my favorite. I got a package deal online by PGY. Pretty easy to find and lots of others. Def a solid investment.

Jump onto the Mavic pages as there is a good explanation for the use of filters from the guys at Polar Pro. I had the ND8 DJI fitted to my P4Pro and it was very good. A lot seem to automatically go for the Polar pro filters but it's all down to personal taste and what you are going to be using them for. I'm not a professional photographer and found the DJI filter to be very good and also fits into the gimbal clamp for the P4pro - The PP ones do not fit.
