I got this really just to experiment with what my iPhone 17 camera could do. The kit you get is very nice. A good case, a microfiber cloth, the clip, and the lens. The lens itself is technically lightweight, but has enough weight to it to show it’s quality.The clip was easy to get on my phone and held tight. It does end up covering part of your phone screen, but that’s ok when you’re using this because you just have the camera viewfinder which you can still see most of.Once screwed into the clip, you can turn the filter to adjust the exposure. There are marks on the rim that show you which ND level you’re at. It’s continuous, but there are 5 marked stops. It’s a litle awkward and fiddly to turn the filter and hold your phone, but it’s doable. I ended up moving the clip a bit when I was turning the lens.It worked as advertised to adjust the exposure in my photos without affecting the color accuracy. It’s definitely more sublte than I thought it would be, but pro-sumer photographers are likely looking for that level of fine tuning.I’ll continue to experiment with this when I need to control the brightness or exposure of the photos I’m taking.
