Been looking for just this... darker ND filters
with an adjustable CP...

Took some video yesterday over rain saturated ground... that drove home the need for CP with a darker ND then stock...

I'm getting a goofy reflection off vegetation when the sun is behind and above me which is visible in the video...

I know it's because the camera is picking up the wavelengths that healthy well watered vegetation naturally reflect...

Been researching the subject for some time and knew I needed to do something at some point...

As DronePilot points out and the SRP website also warns... it will clip the corners in stills...
That's fine, as I can make allowance for it when framing stills and then crop it in post...
Your video was well made and I ordered a set just now to try out myself...

Will post a follow up personal review here in an edit... at a later date...
On edit - yep I can pick out this issue in the below video you posted and am delighted it should help solve my problem...
