SANDMARC Aerial Filter for GoPro Hero 4/3+ - Polarizer, ND4, ND8 and ND16 Filter Pack

First, let me just tell you how hard it is just to find a Polarizer filter for the GoPro and this kit not only has a Polarizer filter but some ND filters! Let’s talk about the build… these are built great. The Kit comes with four lenses that fit the GoPro in a very nice slim storage case.These are marketed for the drone use but you really don’t have to use a drone, I mean the polarizer would be awesome on shots where you can take off your GoPro case. You can not reproduce the effects of a polarizer in editing yet so this is very valuable to have.The ND filters are great for softening the light on video, in photography you can open the aperture to let in more light to stop down a photo… make movement slow.I think this would be a valuable addition to your GoPro and Drone with GoPro!I revived this product at a discount in exchange for my honest opinion.

It does vignette a little on wide picture setting.

Perfect item and it's made my shooting with my GoPro so much better 👍

Working beautifully flying on my 3DR Solo with Hero 4 black. Helps for locking in the shutter speed you want with the ND16! Polarizer works great as well.

THESE FILTERS CAUSE A VIGNETTE WHEN YOU TAKE PHOTOS!!!!!!!I have a GoPro Hero 4 Black and used these filters last weekend on a hiking trip. When you use these filters for taking photos, it creates a vignette which totally ruins the photo!!! You are better off looking for a filter that is wider if you don't want your pictures to become distorted.

works well although not fully tested

Great Product

not polarized don't believe them it's a big lie. I purchased it to use the polarized lens and basically is a ​piece of different level tinted glasses that's it. if you have $40 to throw away sure go ahead buy them but you will end up like me leaving them on desk not useable.
